Hi Doug,

Well certainly my Via M10K box can handle performing HW MPEG decode and
scaling the video to a size even smaller that that which is required,
so it would work very well on my system :)

I think this would be a worth while feature. On my M10K box the CPU runs
at near 100% when displaying this small image rather than the normal 16%
when watching full video. This slows down the UI a lot when using
the "Whats On Guide" or looking for previous recordings.

Has anyone any pointes as to where in the code the small video windows
are done ?
Does anyone know if Xv can be quiered about the smallest video window it
can scale the video down to (This would save yet another config option) ?
