I just got an N3 and I cant get it to play burned dvd's with music videos on them. I have tried burning them on both -r and +r formats, and finalized the disc on both types of formatted disc. I was told I need to convert my files, what file type should I convert them to, and with what program should I do that with? Thanks

convert it to dvd-compliant files with .vob and .ifo files
