This is a recent problem, I have been using WinAvi Video Converter and Cucusoft AVI to VCD for a while with no problems. I don't know what I have done but now they do not respond. I can play videos fine, either via WinDVD or the Microsoft Media Player but cannot convert or split them. I have re-installed them but still not working. I try to import a video but parts of the screen seem to grey out and it just hangs there. Can anybody please advise me. Many thanks.
