Xv certainly works fine with the standard drivers - CPU usage seems
pretty reasonable to me.  I don't think the standard radeon driver has
a VideoOverlay option - AFAIK, it's on by default.  I do get occasional
crashes which I've not been able to chase down yet (either in the radeon
driver or the kernel DRM from the looks of it).

Sure - I'll attach it to this message.  I think there were some issues
with TV out for the standard Xorg radeon drivers - IIRC, you need either
the 6.9/7.0 drivers, or the Gatos drivers (http://gatos.sourceforge.net/)
to get this working.  The support will also depend on what card you have
- ATI don't make the specs for the latest cards available to open source
