Dear Sir!

After 5..6 operations of open/close /dev/video32(0) some frames of video 
become broken identicaly either from /dev/video32 or /dev/video0. It has 
some macroblock shifts/permutate at top of picture:

At last testing i found thet broken frames has periodic in 18 frames,

FRAME[i+0] - hardly broken
FRAME[i+6] - minor brokens
FRAME[i+18] - hardly broken
FRAME[i+24] - minor brokens
..........................

I use GOTVIEW PCI DVD with ivtv trunk Revision: 3149,
Tested with encoder firmware version 2.05.021 and 2.05.032 - result the 
same.

After reloading ivtv.ko problem dissappear, but accur after some open/close.

I re-checked video decoder registers (my own saa7174) in both cases - no 
serious differences.
