I am looking for a program that will trim a .vob file in Vista 64-bit the way "Chopper XP" used to do for me on my old Windows XP machine.

It would also be nice if I could find software that would merge two such trimmed .vob files together.

Ability to convert to something else (mpeg?) would be nice, too, if I could do so without loss of quality.

I have a large collection of archived .vob files that have alreay been ripped from DVDs I made and/or owned at one time or another in the past, and I would like to be able to trim and merge these. I had free software that did all these things on XP, but they don't work on Vista or won't even install on 64-bit.

Please help if you can.
