I'm seeing something similar to that with More4 & other less popular channels on UK DVB-T. The lower resolution or incorrect imprinted aspect ratio causes the OSD to zoom to the left two thirds, with the right third off screen.
As this only happens on one or two channels that I watch, It's not bothering me too much. xineliboutput is exactly what I need at the moment, with my headless recording server and one streaming client - I wanted to control the server osd directly for now.

When I was using softdevice I had a 4:3 TV, but wanted to view 16:9 content in full (so with black horizontal bars above and below video). With this setup, interlaced video would show artifacts. I believe that's been fixed by the kind softdevice guys.

I had issues with audio sync with softdevice too, can't really say how it deals now, as I'm underpowered.
So boxstar will give me direct control over VDR similar to xineliboutput? I hadn't realised that.
At the moment I'm not looking to change my setup, just tweak what I have :-)
