DVB drivers are from kernel 2.6.12.1. DVB-C card is Technotrend's FF 
card (v1.5 iirc).

NTPL is disabled (export LD_ASSUME_KERNEL=2.4.1).

Bug:

DVB driver + VDR: Data stream broken => Emergency exit
-Timeshifting or booting computer up to the channel where data stream 
has gotten broken
     => Emergency exit without possibility to change the channel to
     working one. VDR also does not start automatically when using
     runvdr script.

Solution: if this happens then VDR should change the channel to 
something else (e.g. start from the first channel on the list and move 
forward until working one is found). Alternatively better solution would 
be not to mind about data stream broken problem and show static image 
(error image) and allow user to change the channel.
