Hi, everyone!
Some clarification of the problem:

1. Carefull testing the driver with different tv-programs shows that 
everything  with the tv norm management is OK. In particular, using memcoder 
one can see in its output that the Russia tv-norm SECAM-DK is supported and 
can be choosen by option normid=6.

2. Something is wrong with tv-norm management in tvtime: it looks like that 
instead of  SECAM-DK tvtime set a wrong tv-norm, SECAM-L. In this program the 
choice between defferent SECAM's is automatic, and user cannot manage it. 
There is a question however, either the driver supplies some wrong data (or in 
wrong format) to tvtime, that prevents an automatic choice of tv-norm, or the 
corresponding procedure in tvtime is broken? 
 
3. There is some strange influence of audio channel to video, which is 
probably first mentioned in the post by  Peter Stuge
http://mcentral.de/pipermail/em28xx/2008-December/002277.html.
It results in video artefacts if audio is not used (e.g. by sox that redirect
sound from em28xx  to a main sound card).

Regards,

Oleg
