[mythtv-users] Latest radeon drivers broke vga->tv

[Jose Bernardo Silva]

By now I found that the "ati" driver is "playing smart" and seems to
completely ignore the "Screen" section in xorg.conf, for some
unfathomable reason. So it chooses it's own  prefered resolutions
based only on HorizSync and VertRefresh, and plays havoc with the
modelines I give him. Time to buy a nvidia for my mythtv media centre,
anyone can recommend a half-height passive cooling (silent) pcie
nvidia 7xxx based card? I'm so pissed with ati drivers right now...
