Aw poopie.  Had to move to a PCIx card to free up a PCI slot for
another tuner, and couldn't find a 5200 locally (had a show starting
that night that the wife DEMANDED I record :) ).  Only thing with good
"Myth" related new I could find was the 6200 TC.  SVideo picture (for
X and Myth GUI) is MUCH brighter and better.  But, at the expense of
changing brightness/others on the fly.
