I captured 2 mpeg2 files of 3.5 gigs each then ran them thru TMPGE author to make dvds then reran them thru TMPGE author to make one dvd file. Then I open shrink and open that file, it starts an analysis but stops at around 48% with an error stating "cannot decrypt vobs"- reason unknown. Also when I open the vts file, there is actually no IFO ext.file?? What am I doing wrong?? Thanks
