I'd recommend dropping the 8400 in - I have a gigabyte mobo with the
Radeon X1250 (not the same thing) and couldn't get it working
satisfactorily for DVB-T HD (1080p). The open source drivers haven't
yet got video acceleration
(http://xorg.freedesktop.org/wiki/RadeonFeature) - the Xpress 1250 is
RS600 in that table (according to wikipedia
http://en.wikipedia.org/wiki/Comparison_of_ATI_graphics_processing_units)
so textured Xv is "WIP" and textured XvMC is still "ToDo". YMMV -
particularly if the proprietary drivers are any better.
