I have this card and I am aware that the frontends cannot be used  
simultaneously.  I was unaware of the statement regarding "sequential  
use within the same application".  With even just a little thought I  
can see that this is not at all the same as 'simultaneous.'

It does raise at least the possibility of a VDR setup config to use  
DVB-T rather than DVB-S, instead of the game of symlinks that I play  
at the moment (manual, one time choice of DVB-T or DVB-S, not  
satisfactory and low WAF).

I can imagine that something like this is not a simple addition to  
implement but if there is currently momentum in this direction then  
more 'effort' at this stage will be more effective than at a later date.

I have not given this much thought at all and I am yet to explore the  
potential of the SourceCaps patch.  These comments are really an  
expression of interest in developments of the features of the HVR4000  
(that I imagine most VDR/HVR4000 users share).

Enough of my babbling.

Best wishes,
