I can see

The picture is of my crude 24 cms -> TV band down converter.
It uses an old G8LMW UV02 re-tuned to 800 MHz. The output of
which feeds an ADE-11X mixer. The 24 cms band is down converted
to 440 MHz - 525 MHz. I will need to add some filtering to it but at least
I can see my 24 cms DVB-T signals on my domestic TV now. I don't intend
adding a preamp in front of the mixer as the masthead preamp has enough
gain to compensate for the losses. The UV02 has about 6.5 dBm output
at 800 Mhz around the right level.

I notice yesterday that Xine (courtesy of ffmpeg) can decode H.264 video.
Yes I have tried it and it works.
