I've heard this before, and have this guide as well (nice to see a fellow WSR reader), but the issue becomes one of garbage in/garbage out. If the signal is somehow "composite" in nature, then that's it, you can't by some method "upsample it." If you can ever separate the data into luminance and chrominance at a source level, then it can't be construed as composite, can it?. The NTSC signal encoded on the disc is comprised of luminance and chrominance values, and if they were truly integrated, then providing an S-Video output would be pointless, since you can't somehow "recapture" the split signals. Unless the hidden message here is that composite signal-to-composite-output would be akin to "stacking" two composite processes on top of each other, whereas outputting on some component level at least wouldn't make it any worse. (?) The whole thing gets very convoluted very quickly. In any case, I suppose my experience is as a content provider, where the data is simply data, and can be encoded in any variety of ways, digtially, composite-ly, or component-ly. We do this all day every day, and there's definitely a difference...
