I've never heard of it.
For at last 3 years now, however, I've used the payware
Replay Media Catcher with great success.
Applian, the maker of RMC, has proven themselves to be a leader in this area, and their software is well known and well respected.
You can buy it for $39.95 from them directly at:

In the few instances that it fails (very rare), I'm able to use the
freeware URL Snooper, to sniff out the URL and manually download the video.

For
Hulu downloading, you'll need to use the dedicated
freeware Stream Transport, which is also able to capture videos from some sites. It's not as reliable as RMC, outside for Hulu. See
http://www.streamtransport.com
For
Youtube downloading, and some of those other "viral video" type sites, I find it easiest to just use the
free KeepVid service which gives you a download link to save the video. See
http://www.keepvid.com
Between these few tools, I'm never left unable to download clips.
I'll contact the maker of Total Recorder, High Criteria, and see if they want to submit a full copy for our review. (We don't review trial copies -- there's really no point in that.)
