The cheapest I've seen this side of the pond is an NVIDIA 8400GS for 
something like EUR 90. Fleamarkets/eBay are light on them too.

The machine I have (for use as a combined FE/BE) is an Asus Pundit 2. 
It's SFF (they claim "book-sized") so a replacement motherboard isn't 
really an option. I kind of like the idea of a normal NVIDIA card, which 
is why I started exploring the 1x video card option.

There are two separate fglrx issues:

  1. Corruption in frontend and setup screens when the application is 
running full-screen

  2. "Stacked" video during playback - I get two identical images, one 
on top of the other.

The first problem can be resolved by specifying geometry as something 
other than full-screen, although then mythfrontend segfaults on exit if 
I viewed a program during the session.

At a guess, the second problem might be interlace-related, although the 
MythTV system is connected to my TV via VGA. Alternatively it's caused 
by a misconfigured X11 configuration - unfortunately definitive 
documentation on fglrx isn't easy to come by.
