Hi. I have been having this problem for awhile too. I have non cpyrighted tv programs on DVD (from my cable). When I import the source material into Popcorn 3.0.4. The Video TS Folder crosses over but when a fresh disc is put into the drive of my macbook (os x10.8.3), it almost starts then comes up with a Macintosh OS error.. So what else can I do? Cannot copy my disc and it is frustrating.
