Yeah, I did some A/B testing with four cables: Monster S-video, Monster RCA, generic S-video, and generic RCA. In some cases, I thought there was maybe a bit more chroma aberration (noise, splotches, etc.) with the RCA composite output, but the S-video was definitely softer in more cases. Especially when looking at star fields! Which might not be all that important for many movies, but is sort of an issue for SW...
I figured I'd be able to do a better job of cleaning up chroma junk in AviSynth (et al) than trying to invent resolution and detail, so I went with composite output.
Yes I know that the video stored on a laserdisc is composite to begin with; however, the D925 converts it to RGB for the digital processing circuits, then extracts the chroma and luma for the s-video output. The composite output is the chroma and luma recombined - it would make sense to use the s-video connection and retain the separation.

OTOH, I don't think even the digital comb filters in latter LD players are as good as the comb filters in a decent modern 9- or 10-bit cap card chipsets. Even if it's true that the D925 converts to RGB for processing, that doesn't mean it has to separate Y and C, so no comb filtering needs to occur before composite output. In which case, I'd rather have my cap card take care of that.
But I wouldn't take my word for it: do some testing on your own (like you suggested), and then let us know the results!
Sorry, zion, if this is getting a little off-topic. It's kind of important stuff, I think, but it certainly isn't exactly absolutely necessary in your thread. I think I'm pretty much done, though.
