An idea would be to use "capabilities" : tag your hardware to be capable 
of decoding up to 720x576, 1920x1080, or so, interlaced or not, AC/3, 
etc. and detect in the streams the available parts that fit the hardware 
capabilities. If they don't match, don't display (video) or play (sound).
Many plugins add this kind of capabilities, without explicitly saying 
so. Maybe the core VDR should identify streams and match them to output 
sinks... Or maybe that's just an improvement of the DVB output class
Just my 2 cent.

The FF decoder would probably run into CPU performance issues with 
european HD streams (1920 x 1080). So don't expect to

Instead of investing money in a closed source firmware, you could also 
invest time in an open-source softdevice/whetever ;-) (given that you 
have a TV-out capable graphic card)
