When I first started editing digital video, I had pinnacle plus 9. It crashed my system so many times, that I eventually had to give it a dedicated PC. I installed it got all the updates, then backed up my HDD with Ghost. That way, every couple weeks I could reinstall to keep it from completely locking the system down.
My main problem was that it would just crash with no warning in the middle of while I was doing something and no matter if I had saved it or not, everyting was lost. I got to the point that I had to open and close the program after any major edit or it would crash and I'd loose everything. Not to mention that once Pinnacle introduces a new version, they completely stop supporting any older versions. Pinnacle 9 had so many problems but they figured people would just switch to Pinnacle 10.
Eventually I went ahead an bought Pinnacle plus 10, (for lack of money or knowledge of any other titiles) and it had the exact same problems as Pinnavcle 9. Crash after crash.
I ended up returning it to the store.
Maybe it was my computer you say. It wasn't. I installed on 4 different computers just to test it. Some were mine and some were at alternate locations. The same result with each. My Firend also bought Pinnacle 10 and had the same trouble.
So as I said before... YEE BE WARNED.
