Hi Tom,

As Rod has mentioned, update to the latest versions of all your applications.
I have been checking all my applications for updates compatible with Lion OS X 
10.7 and installing them. It's time consuming, but pays in the end. 
There are updates being released for Lion everyday.

Especially update to latest versions of VLC &  Perian for your issue.
