Ok, this far i know.

1:
I asked on #kaffeine, when ever the problem is software based.
   - Wasn't.
2:
I also had a chat on #linuxtv:
- not problem with bad signal or cabling
I also compiled latest v4l from snapshot.
final statment: mailing list time.

Card is Hauppauge DVB-C ver 2.1 (wintv?) with saa7146_vv (latest snapshot)
So problem is what topic says, everything else works like a dream.

stream example on problematic channel, recorded from kaffeine:

Those problematic channels works fine on hardware digibox on same appartment.
