I recently re-installed windows 7 (with reformatting, so it was a fresh re-install). I reinstalled the AVS video converter program via the AVS4you navigator program (I also tried installing it separately) so I should have the latest version (it's showing 8.4). before reinstalling windows, I was able to load blu ray (yes, i own the blu ray's I try/tried) folders from a rip I did with DVDFAB into the AVS converter successfully and convert them. now when I try, the program (AVS converter) just freezes (it was doing that before, but only for a short while, then the program would come back as responsive). the program shows as not responding in the task manager in windows. I have let it sit for at least 10 minutes. trying to find out if there was a change to the program that would cause this. do I need to install anything additional to fix this. are others seeing this as well.
