What i already did is, use the composite out (HQ circut aka lowpass: off) of the 2950 and made some HDD recordings directly via the 560 (highest bitrate setting). It may sound strange to some using the composite when there is an s-video out, but this just gives the best results. Very natural looking image.
Here is what it looks like:

I have NO problem with motion smearing, checkerboards or the like (scenes changes are also not affected in any way). I use very lets say "convervative" approach on filtering inside the 560. Setting are all set to "minimum" or "full motion" (no temporal smearing). I think Pioneer used all their experience from the high-end Laserdiscs players and put them into these things. The combfilter is great.
If you consider this is just a no-post-live-compression it looks quite nice already (did some high-motion caps to show that there is no smearing). Even more impressiv considering all these fine nets und structures, very hardcore for the combing.
Edit: For anyone interesseted seeing it in motion, a sample of the raw untouched mpeg2-stream from the 2950/560 test-capture (PAL LD): http://www.sendspace.com/file/smyzhi
The most distracting thing for me is the digital compressions artifacts, but like a said, IF i'm going to put some work into it, i'll go uncompressed so this a non-issue.
