You can load VOBs in SW for preview, but be aware that you'll lose synch eventually as you toggle forward and backwards, so it isn't very handy really. Using FPS 23.976 or 29.97 is exactly the same, so take your pick You say your subtitle is out of synch,what subtitle exactly? Can you elaborate a bit? My guess is it's a PAL sub you got off the net, in which case you can load it in SW, input FPS will be 25, and choose ouput FPS as 23. or 29, as said above ;) Then load your VOB in movie preview and check is it in synch now (So long as you let it run without interfering, the timestamps won't get all screwed up). If it isn't , then it would need more work, but I can't much help with what details you gave us.
