.aob files?

im trying to backup my elvis number 1 hits dvd that contains both a video_ts and audio_ts folder.The dvd is 5 gigs and after i ran dvd2one i realize its only 410 mb…what i found is that dvd2one is only running the video_ts and not the audio_ts.Does anyone know how to back this dvd up correctly? email: oo7texas@grandecom.net

Waht the size of the Audio_TS folder and the original Video_ts folder ?

Are you able to copy the AUDIO_TS folder to your HD and with the new encoded VIDEO_TS folder, is it now 4.37gig or less ?
