I have a problem when trying to re-encode avi's/mpegs, or when trying to join two files of the same format. When I try to open an avi/mpeg, the program crashes and locks up. This happens with TGMpeg 3.0Proxp, boilsofts joiner, movie joiner etc., which leads me to believe that the problem is not to do with the software I'm using. I would provide more info if I knew where to find it. Please help.
