I'm pleased to report that all programs which I had a problem with, are working great with latest beta version! Even more: newest revision (3200) of clsid ffdshow doesn't require an old (2322) revision for configuration panel anymore. I''ll check more applications soon. Xeno, Tihiy, big thanks for a beautiful piece of work! Btw, Xeno, you have a volunteer (Ramiro Polla). IMHO, having more brains in your small team isn't a bad idea.
