I have learned the following info :
xvinfo reports, among other things:
Adaptor 0: "Intel(R) Video overlay"
maximum XvImage size 1440 x 1080
So that telling me that the largest permissable video overlay size is
1440x1080 (as I understand it), which obviously won't fit 1920x1080 into it.
mplayer WILL NOT play these two HD channels when using '-vo xv' or
'-xv sdl' as it crashes (with an X error stating it couldn't allocate
space, same error as myth encounters I expect).
mplayer WILL play them with -vo options: x11 or gl or aa (it doesn't
do sound though, but I didn't look into that) The 'gl' is so slow/jerky it's
unworkable, but it at least displays. 'aa' is fun too.
Would it be possible to scale the video down to the 'maximum XvImage size'
(or somewhere under it)?

I will also try this suggestion tomorrow, and advise if it's workable or
