It'll play DVD-Rs fine but if I remember correctly, it doesn't like DVD+R discs unless they're bitset to DVD-ROM.
I can't remember if the N501 likes rewritables or not. (When I got my first DVD burner I went through everything I owned to see what worked and didn't but that's been a long time..)
I'm on a page about incorrect corrections, and spent the better part of like two hours trying to get someone to understand that -5^2 = -25, not 25, and then that post had comments get reposted because that group is self sustaining, and that person was in turn trying to explain what I just explained to them. And I'm taking that as a victory
I will be AFK for a couple of days you guys hold down the fort while I am gone. I will be checking in on my phone but that will severly limit me. Be back saturday!
