The VIDEO_TS folder should ONLY contain three types of files: BUP, IFO, and VOB files. Many people have three folders on their DVD:

AUDIO_TS - contains nothing
VIDEO_TS - contains the bup, ifo, and vob files
EXTRAS_TS - contains the text files, md5, artwork files

So, my guess is that it is the md5 in the folder which is causing the problems.
