I recommend and use Verbatim or Sony (made in Japan)...Taiyo Yuden are TOP quality discs....I also recommend burning at 4X
I like using Verbatim "+". I found out the original DVD are also "+", So I switch from "-" to the "+", burned in book type, and now I can watch the movies in my truck. But I also heard the you get a better burn in " - ", but my truck player will not play a " - " DVD. I saw somewhere in the forum, that you should only use half the disk speed to burn(ex. 16x DVD burn at 8x, 8xDVD burn at 4X).
