I never observed that problem in the short time I had the 6200 running, but
my 5300 arrived today.  I popped it in, started playing video, and began
tweaking the image adjustments.  Turning color all the way down to 0 made
the image black-and-white...sweet.  The 6200 wouldn't do that.

There don't seem to be any motion glitches that I can see.  I'm getting
about 38% CPU usage on an Athlon 64 3700+ (San Diego core).  XvMC apparently
isn't working because of a library mismatch (MythTV was built while the 8178
driver was installed, but I've backed down to the 7676 driver.  I'll need to
rebuild MythTV to see if XvMC is really working again (it was slower than Xv
on the 6200 with the 8178 driver).

I've only had the 6200 for a couple of weeks, so I think it's still within
the return-for-a-refund window.  If not (the memory I bought at the same
time wasn't), it'll end up on eBay.

Another 5300 has since turned up on eBay, with 30 hours remaining, no bids,
and a lower starting price than I ended up paying.  Search eBay for "nvidia
5300" and you'll find it.
