I was able to record both the dvb-s and dvb-t trials until a few days
ago. Since then I've consistently had zero length recordings as well -
not had a chance to investigate further though (runnning svn). Any card
that currently works with dvb-s/t should be able to record the streams
(I'm using nova-t's and a nova-s)<br>
<br>
At the moment, though, mythtv cannnot play the video. Essentially the
BBC have opted to use some of the more advanced elements of the h.264
codec that are currently unsupported in any open source decoder. I've
managed to decode in windows using an Elecard player and codec (trial
version).<br>
<br>
In terms of possible solutions, a patch was submitted a month or two
ago to enable mythtv to use the CoreAVC decoder (Windows directshow
filter) for h.264 playback. This patch works well for me but it does
not yet work with the BBC streams. The CoreAVC developer has stated
that it will have all the functionality required in a week or two -
just in time for the world cup!<br>
<br>
It is however a commercial codec - so you'll need to fork out $20 or
thereabouts, but that's probaly cheap in comparison to the new
processor you'll (probably) need.<br>
