Since I upgraded to 4.09d I had been having both the video sync problem and the audio dropout problem. In fact, the audio problem didn't appear to have any connection to downloading from other's cd's as has been referenced in some other threads. And I had followed all the upgrade advise. I just wanted to pass on that the fix for video sync as referenced in this link (
http://forum.mtu.com/showthread.php?t=2836 ) has also fixed my audio dropout problem. Had my first show last night without audio blipps since I upgraded.
Thanks
