Well here is my problem. I just recently got a new pack of DVD-r's, Verbatims. I'm using an external DVD burner that has been working fine for about 2 years or so. Recently with these Verbatims though nothing I'm burning works quite right. It started with just giving me burn errors a few times. Then when it finally goes through all the way, it plays very choppy on my dvd player. I checked one of my old burned dvd's and they work just fine so I doubt it's the player. The DVD plays perfectly fine if I use my computer dvd drive though. So I'm not quite sure what the problem is. Any help? Some additional info, I normally use Nero 7 to burn, but even when it finished sometimes it would ask me to format that disc still if I tried to open it on my computer, and my dvd player wouldn't read the disc. So sometimes it plays but it's very choppy, other times it doesn't read at all.
