Ok, this is driving me nuts, I went to burn 6 movies in avi files to a generic media dvd-r and i got some error right from the start, then i tried to put on dvd drive in pio mode instead of dma (sp) in bios. both the hd and dvd drive are on seperate ide channels. So i burnt the dvd-r with 6 avi's and everything worked, then i went to play it and i can only play the first 2 movies and not the rest, sometimes i can't even access the disk, when i put the disk into another computer dvd player it couldn't see any files, so then i burnt the same files with a pioneer dvd-rw and the same thing, can't access the drive when i click on it, BUT i can see all the files and play them through nero, im using nero 5.5.8.0. Then i burnt a dvd-rw with simpsons episodes and everything works fine, any ideas? im trying primodvd right now but would like to know what im doing wrong with nero, thanks if anyone can help
