[vdr] PID filter issue with Wideview DVB-T USB

[Matthias Thomae]

VDR experts (Klaus),

I'm experiencing similar problems as e.g. reported in [1] with a 
Wideview-based DVB-T USB stick (Prolink Pixelview PlayTV 505 DVB-T) and VDR.

While the adapter works well with kaffeine, VDR reports a "can't open 
filter handle" error when switching channels *within* a bouquet. On the 
other hand, tuning to a channel on a *different* bouquet works (see 
below). This was tested with a vanilla 2.6.17.4 kernel and VDR 
1.4.1-1ctvdr2 from e-tobi.

As I understand from [2], the problem is related to the hardware PID 
filter of the adapter, which can't be disabled.

Is it possible to find a fix or workaround for VDR so that it works with 
this type of adapter?

I'd be glad if someone with a deeper understanding of VDR could shed 
some light on this issue, and I'd be happy to run any tests.

Regards.
Matthias
