I have just started using Pixela ImageMixer SE version 6 software and have had nothing but problems with it. It continually froze on my system (win 7, 6gb ram, 600gb spare hdd space etc). Closing the software was of no use. I updated it as far as I could, but the later software updates do not recognise the software installed on the computer, failing to install because 'there is no version of imagemixer se installed on the computer'?
I have friends who have given up on this canon software and I doubt I will persist with it.
In fact I am so frustrated with it at present that I do not plan to have anything to do with canon in the future if this is the standard of the software they provide with their video cameras.
A pity as I have found the HFGS21 to be a good unit to date!
