You'll find my post with similar problems mostly unanswered under "VS9 Constant Crashing during Edit"

I too had VS8 and VS9 loaded simultaniously. VS8 working without a hitch, VS9 crashing on nearly every move. When Tech Support instructed me to do complete deinstalls of all ULead products, I was wary (since I have about all of them, I convinced them maybe I could just uninstall VS). Sure nuf, loaded VS9 again and then I was without any VS editing.
So, I did it all again - deinstall (use the complete deinstall instructions you'll find posted, which includes deleting directories and reg files the auto-deinstall does not). You'll want to make sure your PC has all the latest patches. Do a disk clean-up, defrag everything, then reinstall. Try first to run without the 5-in-1 Patch. If you crash, load it (I had to). That helped a bit. I was running, but still crashing.
Looking at the posts, you'll find several suggestions. I turned-off write-caching on my hard drives. That seemed to help a bit too... but still crashing frequency made it an unusable state.
I talked to Tech Support again, they're really more "how-to" folks and were no real help. This board has more ideas.
There are posted recommendations not to load a codec pack, so I didn't do it. I did, however, find out there was a new ATI Catalyst install available that I loaded it. MUCH better. So, there are some compatibility issues with VS9 and legacy configurations.
I also read on the boards about file integrity and issues with previous capture/render versions. I'm suspecting that there may be some corrupted AVI's involved because I'm crashing when working on some more than others. All were captured in VS8. I'm not sure what's going on with that yet.
Oh, and you may have trouble burning DVD's. I had to install the Burn Pack/Patch that was release during VS8 (at the recommendation of Tech Support). That fixed that problem.
