Latest update broke SourceTV recording?

I have a problem since the latest update (July 27, 2009), it gives me this error when trying to play a source TV demo:

The number in brackets is different on each demo. The server and my game have the latest update, it happens with demos recorded after the update (demos before won’t play but give a different message) and I’ve only had this problem since that update.

Clientside work fine, even if recorded on the server.
