 dvbrecorder listens currently on each pmt pid in the pat. On some
 multipplexes this is to much for my Fujitsu-Siemens Full-featured DVB-C
 card. It can't open more than 27 filters. Unfortunately it fails hard and
 needs a driver reload to recover if you try to open more.

 So this is mainly a driver issue but it's stupid to listen to all PMTs.
 Attached is probably incorrect since _pat is NULL when AdjustFilters is
 first called. Nevertheless it works since _input_pmt is already correct
 (probably cached from the signalmonitor).

 An error report on the linuxtv mailinglist resulted only in a change in
 the dvbscan utility ([http://www.linuxtv.org/pipermail/linux-dvb/2005-
