I updated it to SP2 and as soon as it launched, a bubble popped up that said "Capture duration in the Standard version is limited to 10 minutes" and I was like What!!! It says the opposite on the download page. So I tried a capture of >10 minutes and it seems to be fine. Dunno. Filesize was about 250MB for ~11 minutes at ~25fps, which I think is fine.

Thanks again for the suggestion.
