Hello-
Chalk it up to software voodoo for now?
If you have any further insights into the problem, or it happens again, please do let me know.
Hi.
I've just discovered Snapz Pro and downloaded it, and I'm suffering from the same software voodoo.

The problem is exactly as described above -- a solid green line from top-left to bottom-middle of the playback window.
I'm on an iMac G5 with all the latest OS patches and updates. I saved the video as a low quality MPEG-4 file.
However, I uploaded a video to YouTube to be able to show you the problem, and guess what? The version on YouTube is fine! This prompted me to try playing my local file using different software and platforms, and it appears that QuickTime and RealPlayer on the Mac both exhibit the green line problem, but QuickTime and RealPlayer running on WinXP don't. The video also looks fine when viewing the YouTube version on a Mac.
You can see the video I've uploaded here:
http://www.youtube.com/watch?v=MjC57dsx6NA but to be honest, there's not much point, because it doesn't demonstrate the problem at all! I'd be happy to email in the file (~2.5Mb) if it'll help diagnose the problem.
On this occasion, I only want the recording for embedding in a website, so the YouTube copy will be fine, but I'd still like to get to the bottom of the problem before forking out my $69.
