Sadly, last night I was working late, and was tired, and managed to delete a chunk of my grabber recording source code. The bad news is that I didn't have it backed up, so I have to rewrite it. The good news is that hey, I get to rewrite it!
Seriously, it's only a few hndred lines of code, and I pretty much remember exactly how it works, but it was reasonably subtle, and might take a bit of tinkering to restore. I'll try to get it going Saturday.
