I tried watching Quicktime movies in both CoolVL Viewer & Firestorm and they would not play. I downloaded the latest Second Life Viewer as suggested to test it and the movies played fine in that viewer with no problems at all. I'd rather be able to watch them in CoolVL viewer than have to relog using another viewer.

I love CoolVL Viewer.
Here is the info requested.
