Dvd burn

hi,
newbie here. followed all instructions on dvd2one implicitly. after writing to dvd via nero the dvd will play in my pc but nothing happens when i put it in my main dvd player just an error message. also it does not autorun and only plays with wmp.

seems to be i am missing some instructions etc, have wasted 4 dvds so far, expensive eh

Were you using +rw or just -r?? That can get expensive.

try re-encoding the file.
