I have it and like it; see this link for more info. Commercial detection runs about 7-8min/hr for over-the-air MPEG source data, and about twice as slowly for TVE H264 files (not sure why, there). COMSKIP works on a single thread leaving plenty of other resources.
Also, with recent beta builds, hardware acceleration is enabled and it can transcode and stream 720p and 1080i with fairly low loads (<150%).
