It's supposed to do that,at least for supported Matrox cards. Well, I 
tried something last night, but no success yet.

Some Freevo developers are already addressing this, if I understood them 
right, they're using streaming in any of the various paths the're trying 
(vdr-xine, sofdevice or completely new client), so a vdr deamon should 
stay alive all the time taking care of recordings, and if one wants to 
view live TV from within Freevo, vdr-xine, softdevice or another client 
might be started and will connect to the deamon which will run with 
streamdev-server. Another approach, if I understood them right, would be 
to controll everything in a completely new client with "freevo-native" 
OSD via SVDRP, and again streaming. I think it also needs further 
improvement in streamdev, not to stop streaming on switching channels 
for example, I think it was already discussed with the streamdev author.

Well, I think I won't downgrade now the whole DFB stuff. Eventually 
softmpeg some day will get some more attention again...

Yes, that might be a solution. Thank you, I was involved in some of 
those threads myself, too. Nevertheless, I still have some strange 
issues with DFB initialization of the TV-out. I have to dig further...
