I downloaded spiderman 1 2 and 3. i used convertxtodvd to convert. and i made sure i put it as NTSC. It finished converting. I opened nero. i entered the dvd burning part. I added the first movie files. like this VIDEO_TS.BUP then VIDEO_TS.IFO Then the movie files. I click next it said it reallocation started and finished cache started and finished, the burning start and finish successfully. When i put it in my DVD player it read there was a DVD it said Dvd in the corner then it press play. Then the DVD PLAYER STOPPED. SO I put it in my PS2 and my playstation said something about it stopped because of a malfunction. Im not sure why this happen. so i tryed to burn it again and I got the same results so now im asking for some help.
make sure your using good blank media like Taiyo Yuden or Verbatim even Sony burning at 6x to 8x max give imgburn a try also instead of nero
Next time purchase the movie(s) so you legally own it/them. Otherwise sounds like a pretty clear cut case of poor blank media, as has already been stated.
