Movies from my laptop

U

uh...ok

Guest
A strange occurence tonight as I tried to play a DVD on my laptop...

My Residence-Based Advising seminar group meets weekly for a dinner and a movie on Sunday nights... and tonight we finally got to use the nice new room with a $40,000 projector in our cafeteria. Unfortunately, we were not allowed access to the DVD player in there (no one had the key) so we had to run the movie off a laptop.

Our professor's laptop would not display on the projector, so I volunteered mine, since it's so cool and all.

So I get the laptop hooked up to the RGB plug and set my display to both LCD and CRT. And voila, it works. We can see my cool DigitalBlasphemy wallpaper and my nice, clean, aesthetic desktop on the huge projector screen. Pop in the DVD, load up PowerDVD... and the movie runs fine on my laptop but nothing shows up on the projector screen.

I try using a different DVD program, WinDVD, to play it. Same thing. We can all see the program itself and all the windows things, but when it comes to actually playing a media file, we can't see anything.

I thought it might be the DVD's fault, so I load up Windows Media Player and find a random .wmv file to play... same result happens.

The situation's analagous to trying to take a screenshot of a scene in a movie on Windows Media Player by using the PrntScrn function. You get the screenshot of everything but the movie itself.

Does anyone know if there's a way to fix this, and if so, how?


-uh...ok
 
The screenshot thing can be fixed by go into the program's options and disabling "hardware acceleration" and things like that. Might do it for project as well.

Also try playing with the resolution.
 
yeah, my guess is the resoluation. The laptop may change resolution so that movie takes up the entire screen (not expanding the movie, just the res.. ya know?) Try not doing it fullscreen, but expanding the window to where it is almost fullscreen... i guess you can't try it right away, eh?

What brand is your laptop, and what's the make and model of your video driver? Do you have options to set a secondary display in your display options (Contol Panel - Display - Settings)? I know that for ATI cards to show DVD playback on a tv, you have to set the tv as primary, and your LCD as secondary, but I haven't tried a projector (as you say, they cost a bundle). DVD playback should only be visible on the primary display, which may be why you couldn't see it on the projector.

If you don't have an ATI card, post back and let us know what your specs are and we may be able to help further.
 
I have a Toshiba Satellite S501. I have a GeForce4 440Go 32MB with NView enabled.

And the laptop (like many modern laptops) has a function key that allows it to switch between display modes. I have 5 modes: LCD, LCD/CRT, CRT, LCD/TV, and TV. I set it to LCD/CRT.

As I said, the entire resolution of my desktop shows up on the projector screen. Just the DVD playback does not show up. Nor does playing and Windows Media files.

I have yet to try disabling hardware acceleration... perhaps that may work... perhaps it won't.

Thanks.


-uh...ok
 
Check your video settings in PowerDVD - overlay mode and all that stuff.
 
Did you try the CRT mode, rather than the LCD/CRT one? Any different results?

I got this off a page talking about configuring Nvidia cards to play DVDs on a tv, but it sounds from what you've posted that this is pretty much what you've been doing... I'll see what else I can find - sorry I couldn't be more helpful.

B. Settings for Nvidia cards:
1. Right-click your desktop and go into properties
2. Select the Twin-View tab at the top of the properties dialog window
3. Select Advanced (toward the bottom). There will be three options and the TV option should be available now - click the TV option and select whatever video type you want (composite video for example).
4. You will have about 10 seconds to confirm the connection which you will only be able to see from the TV.
 
TV mode won't work because that's A/V output. Not RGB.

So far the only thing I haven't tried is setting CRT as my primary display.


-uh...ok
 
Yeah... I threw up the tv info just as a comparison, since the general process is the same, although obviously you won't get the desired results from those steps. I couldn't find any similar user-info posts for projectors, so that's the closest I could come up with. Let us know if setting the projector as primary display works, but I would have thought that twin-view would have worked (for presentations, etc.).

    Mayo also has vinegar. Vinegar is a very important part of it, it's effectively a delivery method FOR vinegar but hidden

    It's a neat ingredient. But yeah it's eggs. But a LOT of people think eggs count as dairy because of the fucking food pyramid the US keeps trying to make a thing
  • Varine Varine:
    I think on the new one they did change it, but idk. I don't really care whatever the government is doing right now because it's consistently absurd. Like what is RFK doing in charge of health anything? I love the bear story because WTF was that, but also, pretty much every time he talks it's WTF. Like even his voice sounds microwaved

    The pyramid is fucking dumb as shit, no matter how you arrange it.
  • Varine Varine:
    It's actually remarkably easy to make mayonnaise though. Fun fact, it USED to kind of be a French mother sauce. I believe that Careme considered it one, it may have been aioli but that has also built a different meaning than it used to. An aioli is just mayonnaise I mixed with other shit typically, I didn't start it don't come at me
  • Varine Varine:
    It's very hard to do it on a large scale though
  • Varine Varine:
    Depending on how you pour the oil the consistency can vary wildly, but that's true for most emulsions. I can only make about two quarts at a time with my robo coup, and if I have to make several in series because I forgot to order it becomes really obvious even when I do it. We have to wait and mix them all together to make sure we have the same thing.
  • Varine Varine:
    Hollandaise is also kind of like that, emulsions require a very steady hand to do exactly the same every time.
  • Varine Varine:
    Luckily I live in an age with electricity so it's way fucking faster, but when I was just a boy trying to find my place I had some hardcore chefs that made use do things like that by hand. It is WAY easier to get right by hand because you control it and can feel it, but it takes soooooo much longer. And on the scale a modern kitchen requires... I serve 400-500 guests on average per day right now, if I had 100 then we could do things way better
  • Varine Varine:
    But we can't do that. In the winter yeah, but I HAVE to get people through here right now so I can afford the staff that we CAN do that. We have about 100 days of summer, and if that summer doesn't make us what it will, then I can't operate the other most of the year with my staff. The owner is talking about closing two days a week to cut down on labor, I told him he should cut down on vacations and it did not go great. I do think I won though, I have to keep my fucking core staff and they have to be gainfully employed
  • Varine Varine:
    Sure some of them might take a second job, but I can't just cut my entire staff to unlivable hours, nor can I can cut them off all winter if I want them to come back.
  • Varine Varine:
    And also, there is no fucking way I'm pulling these hours come september. I only do this right now because I have to, the second I don't have to be the one doing it I won't be
  • Varine Varine:
    I have a 5 person core staff in the kitchen, not including me or Chef Ben
  • Varine Varine:
    Though two of those people are likely not making it this year. One of them has been replaced, the other I am kind of trying to. He's being a giant bitch, today I had to get onto him because in the three hours before I left he had taken like thirty minutes for cigarette breaks
  • Varine Varine:
    And he was also complaining to me the other day that he was out of weed so couldn't smoke any before work that day, and was confused about why I was annoyed he was telling me, his boss, that he is smoking weed everyday before work.

  • Varine Varine:
    Like yeah I can tell. I don't need to fucking know.
  • Varine Varine:
    So now he's getting scrutinized and will not be top of the list. I know I don't have the smartest people but I do expect them to have some common fucking sense
  • Varine Varine:
    I did do a rare thing for me and hire a girl last month without warning. Everyone was made at me because I started her at like 21, but she worked with me before and I was like don't care. She made 19 at her old job and I wanted her to come work with me, she is the best

  • Varine Varine:
    I'm going to get her a raise at the end of the summer. She wants to go to school again, but I want her to still work with me so.... she kind of can just tell me what the price is. I can go to 25 if she keeps up. I need to get her onto line more, that's what she wants, but I need her where she is and it's not fair that she doesn't get the little bit of raise that comes with it. She can do it no problem, I've worked with her there.
  • Varine Varine:
    It's just hard to move and train people unnecessarily right now. And also the line fucking sucks, it's not any more fun. This is turn and burn so I have the bankroll, and everyone suffers for it
  • Varine Varine:
    Eventually we'll get it balanced, we'
  • Varine Varine:
    we're starting online orders and stuff, but I also turn that off all the time because I barely keep up trying to be the best at Sysco shit
  • Varine Varine:
    I think it's gonna be a good fall and winter though. We're going to have a good staff, they will get along, they will be able to manage the workload and the complications, they know how to really cook this year, like every person on line knows their steak temps. Some of them use thermometers a lot and they don't always use them right, but they do know how to do it. Failure, especially in this field, is the only way to get better. They'll get it
  • Varine Varine:
    They won't get feel down while they do the thermometer, but we didn't have an instant read probe when I was learning. Like they did but god knows how off it is, you HAD to do it by feel. Even if the chef was fine with me bringing my own, it takes too long. Poke and know
