Well, then it HAS a lot of hardware horsepower, obviously ;-)
Earnestly it's no problem at all, no quality degradation when doing both
at the same time. It has some problems when doing the third thing it
does: Displaying the framebuffer, but that's a driver related issue with
interrupt handling and driver threads.
The Sigma card might be interesting for YUV overlay, hardware scaling,
but as you found out:
