VitualDub works perfectly! Its perfectly stable. I'm realy grateful to you. I cant believe, after all these weeks of struggle, (reinstaling drivers, rebooting, loss of audio etc) that the might of Microsoft and Ahead have caused me so much grief and that this guy wrote VirtualDub whilst he was at college!

This has been a lesson to me. Just because a program costs a fortune and looks flash doen't mean its the best.
