I installled Vista 64bit SP2 and Adobe Media Encoder stopped working. Anyone else had issues with Vista Service Pack 2?

Hi David, check out this thread, http://www.dvinfo.net/forum/cineform-software-showcase/236131-vista-64-service-pack-2-a.html.

There doen't seem to be problems according to this thread. You don't say what version of Premiere Pro CS4 you are using so maybe you need to update to 4.1 or 2.
