Hi, I seem to have lost the ability to see any video in the viewer. I can hear the audio fine but I can't see any video. Any idea's??

One common cause for this is an old FCP bug. Set the viewer scale to "fit in window" and NOT to 100%. Also, be sure to close the log and capture window when not using it. Sometimes strange things like this will fix themselves by quitting and restarting the program also.

oops! I had the viewer set to wireframe view, I just had to switch it back to view image. Thanks anyway Boyd

Yep, that'll do it also :-)
