Not possible. Hardware MPEG-2 encoders are designed to encode data  
from on-board analog inputs only. What you're asking involves MPEG-2  
decoding as well.

Not really. ffmpeg isn't designed for symmetrical processing, so it  
will only use a single core. However, this will benefit you if you  
this box for multiple things (front-end as well as transcoding,  
etc.). You'll see a benefit there, as the other core will be free to  
do your bidding.
