You may remember me from such threads as Gimme miracle TV, in which LocalH posted a link that incidentally provided some background information about, but no solution to, this issue. Whereas that was slightly more general, I think this sufficiently technical to warrant posting here; move it if I've judged wrongly, of course.
In short, my Saturn looks terrible on my CRT TV, to which it is connected via an RGB SCART cable. Or rather: it looks pretty great until things start moving. Then there's interlacing everywhere.
This shouldn't happen, should it? The Saturn almost always outputs 240p, an LDTV format that should be supported by almost everything. I'm presuming my TV isn't familiar with this—possibly because of some difference introduced by the NTSC encoding?—and therefore is trying to deinterlace a signal that isn't interlaced, thus creating novel interlacing.
The TFT doesn't look great with the Saturn either, but the problem appears to be upscaling and not interlacing. That figures, since the TFT can handle NTSC signals better in my limited experience.
Wat do? I noticed this a few years ago (when I last played my Saturn ;_; ) but had less knowledge of video-related phenomena such as interlacing, so I was just as likely to attribute it to a bad output and/or cable as to the encoding. Is it as simple as needing a better TV? Tell me this isn't some unique problem of my lovely skeleton Saturn! TELL MEEE. I'm fine with buying a new cable, but I have no idea how that could be the cause.
