The sounds is not transferring or is corrupted, I am able to back up to an *.avi using DVDFAB 6, but it doesn't have all the new capabilities. Have you looked into this problem? It is with older music videoes, with PCM sound. I have noticed it a couple of times with Blondie, AWB, and others. Also, when saving the files, it takes a long time to change the file directory. This is using the latest software release, but I have seen the directory problem for some time, when converting to a *.avi and saving it on my computer.
