Having only recently tested DVB-S2 feeds I find that they work to an
extent, there is more testing required, however, I don't think I 
will be using that feature as there is nothing for me worth watching
at this time.

I have started looking at that but have no progress report as yet...

Ok. This is understood. Personally I am keen to get the feature set proven
to work for my own personal consumption. If anyone is actually interested
in helping, for example, testing the hvr3000 in the hvr4000 tree then
please e-mail me.

I originally created some patches to do just the above in March. I have now
updated those for anyone who really wants the hvr4000 running in v4l-vlb
right now *without* DVB-S2 support, but, I am looking at the merge of those
disparate trees mentioned above and may not be able to maintain this. Maybe
someone else will pick it up?
