Again....this is one of the weird issues of the Pinnacle Studio software. I had the same problem AFTER I applied the latest patch. I called Pinnacle Tech but they were scratching their heads. Then I closed/restarted the application a few times and it eventually it worked----it's a miracle. Pinnacle tech support still has no idea to what's going on....they said "well if it works for you it's fine with us...??????'...whatever that means.
