Right, terrestial is the problematic one.

Celeron 2.6GHz for my softdevice tests

There are blocky low and nice high bitrate channels on both transports. 
On a 800 MHz C3 I think there is no significant difference. CPU load is 
normally 5-10%.

Mplayer (CVS version) which uses ffmpeg as well doesn't have the 
problem. Streamdev protocol is different and ffmpeg versions are 
different so it doesn't prove that ffmpeg works. Now I remember that 
there were some terrestial stream issues with dxr3 plugin too in the 
past. I'll check the archives if I find what was observed.
