I just downloaded the beta version of DVDFab that I linked for you. It installed perfectly in my machine. And I don’t own the main program, so I just get the free section, but it is working just fine.
Have no idea what is going on with your setup. Best to start a thread in the DVDFab forum if you are having problems getting it to run.
Conversion PAL to NTSC can be done with ConvertXtoDVD supposedly…there is no fully functional trial of the program. Their trial puts a watermark on the video. The Film Machine also claims this capability…and you can use the free HC encoder with it. HC is an excellent mpeg2 encoder by the way.
Some people have had success using FAVC or AVStoDVD even though this conversion is not one of their primary functions. They are both setup to use DGPulldown, so that will help in this PAL to NTSC conversion. Both of these can use HC as well.
The Film Machine, FAVC and AVStoDVD are all free programs. ConvertXtoDVD is not.
By the way, if you can’t get DVDFab HD Decrypter going very soon, you can always download the free trial of AnyDVD and use it for 30 days. It will break encryption in the background and allow you to use DVDDecrypter or DVDShrink as the ripping program if you wish, though on some of the newest movies with the nastiest protection you might want to use the built-in ripper.
