Hmm. Could you try with a newer driver? Not that I'd think there are any fixes
which could affect it, but you never know...
Otherwise, it looks like either xpress 200 chips (all of them?) don't support
planar yuv, or need a somewhat different setup - both of those seem a bit
strange considering the overlay is pretty much the same for r100-r4xx (and even
older ati chips, actually). We'd need some input from ati to confirm, or
someone could spy on the overlay regs while running fglrx (and using
overlay-based xv).
Of course, the old code to convert it to packed yuv in the driver could be
readded (removed it as all radeon chips I knew of supported planar yuv just the
same) for those chips, but it's certainly not as efficient as using planar yuv
directly.

If you're using a monitor with a horizontal resolution lower than 1920 you're
unlikely to ever notice. I've tried with 1920 and it still looked great - I'd
guess you'd need direct comparison side-by-side to really see it with normal
video source material.
