BurnBaby - 2012-09-15

I have several DVDs created using Burn, which play for about twenty minutes and then quit.

It seems that I mistakenly burned the VIDEO_TS folder with "Data" and "DVD (UDF)" selected in the Burn application, instead of "Video" and "DVD-Video". I assume this caused an incorrect burn and now something is scrambled in the structure of the DVD. It looks like all the IFO, BUP, and VOB files are there, but something is messed up.

Is there some way to recover from this? Can I copy the files from the "broken" DVD, tweak them or somehow re-burn to get a DVD that plays all the way to end normally? Is there some other application I can use to validate the DVD structure or identify errors?

Thanks much for any help with this!
