Initially, when it worked, I was satisfied. However, several weeks ago it stopped working.
I tried uninstalling and reinstalling; when I launch the installer, it says an instance of the program is already running.
I've emailed Cucusoft's tech support seven or eight times over the past month, and always get a scripted answer, which tells me to do what I've already done. Sent them screenshots, etc - never get past the 1st tier support. Save yourself a lot of grief; get *advertising* Ultimate Video Converter.
It's faster, has as many conversion options, and their support staff appear to respond to questions (I've emailed two so far and have received usable answers within an hour).
