Who aren't forced to use the feature.

I _can_ stream all channels at once. In my setup I've got multiple DVB cards
and a multiswitch. Therefore, there is no problem recording multiple
transponders at the same time. Since in germany the "main channels" are
concentrated on only two transponders, there is no problem at all. As I
wrote, I can record 7 of the 11 most prominent german channels at once using
two DVB cards.

Klaus did a very good job with VDR, I agree. However there are still things 
one could improve. 

You're probably right, that on a full-featured DVB card that is not running
in transfer mode, nothing can be improved. I don't own one, therefore I
cannot say anything about that. However, if a DXR3 is used as video out
device, the channel switch takes a while. I don't think that this is a DXR3
problem (but I'm not sure). The most obvious explanation for the delay seems
to be that vdr needs to wait for the next I-frame after the channel switch.

That's of course his own decision.

Ciao,
