I'll play with it.
In the meantime, could someone explain why watching live tv is more
intensive than watching pre-recorded shows? Because of the buffer kept
on hard disk? Would it be impossible to watch mpeg4 on this box then
(more cpu intensive as far as I know)?
About the Openchrome driver: is it the recommended driver in all
cases, or is the Unichrome driver a better choice if you do not intend
to use XvMC?
