Interesting. I'll look out for it on my next MythTV build in five years or
so! :-)

I'm patient; I've put up with odd double-scanned half vertical resolution
output on my TV for the last four years or so of running MythTV.  I'm
pleased to see that between the VGA card upgrade (from a 440MX to a 7600GT),
the nVidia driver upgrade, and MythTV upgrade, it can now do full vertical
resolution Xv with interlaced low pixel clock modes.  :-)
