This is perhaps related to a problem I am seeing.

I am using vdr 1.1.15 with driver dated 1-11-2002 on a DVB-s 2.1.
If I tune from an active channel, to a channel with no carrier (my 
channel list has channels that carry itinerant feeds), and then tune 
back to an active channel, the vision and sound does not return. VDR 
still seems to be functioning OK (OSD changes as I switch channels, 
menus work), but I can only restore vision/sound by restarting VDR (not 
the driver). While it is faulting, the kdvb-fe process is using 50% CPU 
(P1 233).

There is nothing out of the ordinary in the log and Klaus was a little
baffled by this behaviour when I reported it on the VDR list.

I will test with the latest CVS driver.
