when you burned, did you select DVD-Video format? I think you selected DVD DATA instead, right?
copy the files back to hard drive then burn another disc, making sure to select the DVD-Video format...then let me know if that works for you
EDIT: also, if ur burner software does not create this folder: AUDIO_TS then u need to create it, at the same subdirectory level as the VIDEO_TS folder. The AUDIO_TS is just an empty folder but it does need to be there for the widest compatibility with standnalone DVD players
