Hi Guys. I have a Z1U and do videos to upload to Flikr. I am fairly new to this and have been able to upload only 2 vids so far. I had no problems doing that.

At the time, I was using Win 7 x32 and Pinnacle Studio v.12. Files were avi. Since then I have used Win7 x64 and Pinnacle Studio v.16. I have not been able to upload a video, despite attempts with .avi and .mpg files. Every time I attempt an upload, it fails after about half an hour. Generally file sizes are between 170 mb and 360mb.
Is it possible that the failure is caused by the x64 OS?
