I have copied off BSG disk 3 using dvdfab5 which seemed to work fine.
Next I reauthored the files using dvdshrink to create the 4 episodes i want to keep.
Using those 4 files i then used simpledivx 1.40.25 to convert to divx.
However I get a mencoder error as soon as i start the conversion.
This method worked fine with disks 1 and 2 so is something more tricky with disk3?
The vob files play fine with vlc.
thanks for your time
