I have ripped,encoded, decoded DVD's onto my HD. No probs. However, with a few, I have problems playing on a standalone player. Is there anyway to test play the DVD files on my PC before ripping to DVD ? For example, i create the relevant IFO files along with the correct VOB files... I do all the correct processes, ie. VOB Extras (correct navigation pointers etc) and Get VTS Sectors... When i open the VIDEO_TS.IFO file on my PC using PowerDVD it plays fine, no probs. SO, i then rip to DVD and it does not play on standalone, or simply plays first chapter!! What I want to do is be able to test the files I am going to burn before I do, therefore not creating too many coasters !! Is there any software that enables this ? I know IFOEdit has DVD Play button, but does this truly check the files ?
