How about making a "thumbnail video" of every HD-recording, say by using nearest-neighbour method and taking every 4th sample and every 4th line. This would make a fairly small video but still accurate enough to run comskip lightning fast on. Normally it takes me 3-4 hours to run comskip on a one hour HD resording.

What are you talking about? We're just talking about showing some jpg's in the UI.
Its not something I'd build in, but you can probably run some transcoding job in PostProcessing.bat or Parallelprocess.bat if you need a small version of the video.
It definitely wouldn't be worth trying at recording time - nobody wants to use all their available CPU decoding+resizing+reencoding on the fly.

FYI: This situation sounds like your CPU or disk drive is way underpowered for comskip. My system has an AMD Phenom II X3 2.80 GHz processor, and comskip usually takes about 15-20 minutes to process a 1 hour HD recording. And that is with multiple (up to 3 or 4) simultaneous recordings and/or comskips running.

I have a sata-II RAID array and a dual core 3.0GHz AMD processor, so it should be enough power. Normal SD recordings takes about 10-12 minutes, but a full HD recording is 5 times more data. The time comskip uses also depends on how many algorithms is applied to the recording, and to sort out commercials I found that I need at least four. I can cut the time by skipping the lower 50-60% of the oicture, but then the accuracy goes down.
BTW: it does not matter if the computer is idle or there are 3-4 recordings going on, so that does not indicate any bottleneck in the disk speed.
