It's hard to recommend 260.xx drivers to anyone using mythtv. And to stick to 195.* or 256.*
With 260, there are plenty of visual artifacts, crashes. Playing video with vpdau, if you interrupt it, you end up with the last video frame played in greyscale on the desktop.
Bit regression with 260.
Luckily I found that my GT430 works with the latest 256 drivers
