Ok, heres what I got. Amd 2100xp, 512 ddr, Win XP, Toshiba SD-R5002 DVD-Rom. Using DVD r-. I have no problems backing up dvd's, when done I try to play them in my Panasonic player, (which says can play all DVD R - or +) In the panasonic, one video came up fine, but was choppy, like it was skipping, all the way through the movie. Next movie would not even play. On my laptop, the skippy movie would not play with Windvd, but played fine on Windows media player, second movie would only play sound on media player, and no where else. I updated to the newer version, and same thing. Any suggestions??
