I ripped a backup copy of Kangaroo Jack with DVDDecrypter 3.1.6 file mode and full disk. Used DVD2One full disk, constant ratio, one audio. When I hit start a popup said
UNABLE TO OPEN VOBFILESET 0 IN DIRECTORY D:\KANGAROO_JACK\VIDEO_TS. I hit OK and it looks like the compression starts. Did not check if it finished the movie yet, will let you know.
P.S. Just read that if your using constant rate choose
movie only for movies over 21/2 hours. Tried movie only with constant rate does not give the popup. The full movie compressed with constant rate seems to be working fine even though I get the above popup message.
