So I guess I should try the $21 TYG02 then?
The best answer is -- are you going to play these discs on standalone DVD players, and if so, are you limited by what kind of discs THEY will handle? Have you checked to see if your other DVD players can handle DVD-R, or DVD+R, or both? This is often the determining factor.
If all of your DVD players can handle either, then you should definitely look to the DVD+R discs, since the above post is 100% correct -- for some reason Lite-On drives are famous for working better with the "+" type of disc. (This does not meant they will not work with the DVD-Rs, though, you just have to be a bit more careful about choosing quality media).
