There are fanless Nvidia cards that do what is needed.  They usually
take up two slots due to the massive heatsink, but then lots of more
powerful normal Nvidia cards use two slots anyway for massive fans.
Apparently the bottom end Nvidia chips usually used in the current
generation of fanless cards are good for anything MythTV needs now,
unlike when I got my fanless Asus Bravo 220 card - back then the
Nvidia 210 chipsets did not have enough capability to do full
"Advancedx2" hardware deinterlacing, but could do everything else.
