I don't use a deinterlacer, and it looks fine, so I'm guessing that
there's only one vsync per frame.  I have an AMD 2500+ Athlon.  I
normally use XVMC for HD, and that works pretty well.  Without XVMC, I
can still do HD, but if anything else is running, it starts to hiccup.

The 5200FX is fanless, but apparently shouldn't be; I've had two burn
out, so I've bought replacements on eBay.
