[vdr] VDR constantly adding and deleting filters

6 May 2008

Hi all!
While debugging another issue, I noticed (ADDF/DELF streamdev traffic)
that VDR is constantly adding and deleting filters in cPatFilter::Process().
As I don't know of this filter stuff, I ask here:
Is this correct behaviour?
It probably is, but I just want to be sure :)
Below is a log excerpt with the attached patch:
