[vdr] CinergyT2 "frontend timed out" when switching to ARD

[Matthias Thomae]

Hello,

I've been trying to get my Cinergy T2 USB box working properly with VDR, 
but I get the "frontend timed out" error message sometimes when 
switching to ARD (or another channel in the same bouquet), and the 
screen remains blank (error message below). The 'sometimes' varies from 
2 to maybe 20 times.

After the error occurs, I can still view other channels, but none in the 
ARD bouquet. Restarting VDR doesn't help, neither unloading/loading the 
cinergyT2 kernel module. After unplugging the USB cable I can again view 
ARD until the error occurrs again.

I tried with VDR 1.4.0-1 and 1.3.49 from e-tobi.net, kernel 2.6.17-rc4 
and 2.6.15.5, on 2 different machines (one with the USB box only, one 
with an additional full-featured DVB-S card). The CinergyT2 is running 
firmware 1.08.

There are similar reports on www.vdr-portal.de, one claims the problem 
vanished after doubling the CinergyT2 kernel tuning parameters and 
changing channels.conf entries from I0 to I999 
(http://www.vdr-portal.de/board/thread.php?threadid=50153).
I also tried this, but the problem remains.

Any ideas?

Regards.
Matthias
