This may help solve the problem...
I have been using Ulead Video studio since V6.
I recently Upgraded from VS10 to V11-Plus and everything worked perfectly. Both Firewire and composite captures gave no problems.
I then upgraded my PC and had to re-install VS11-Plus..
The upgrade consisted of Motherboard, Processor and Memory (Kept the same Graphics Card)
Following the re-installation, I couldn't capture with firewire, each time I tried I got the "Cannot Start the Capture Graph" error
I googled the problem and looked at many forums where people were having the same proplem for about 3 days. I then sent a support request to Ulead/Corel, which I haven't had a reply from yet..
After trying to work out was different, I remembered that I hadn't re-installed VS10 since the rebuild whereas it was installed on the old system, because I hadn't bothered to uninstall it.
I re-installed VS10 and I can now capture using firewire in VS11 without errors.
Does this help the technical people out there... What does VS10 install that VS11 doesn't.
My problem is solved because I don't mind leaving VS10 on the hard drive if thats what it takes to make VS11 work.
I hope this has helped someone
Happy Christmas to ALL
