Analog TV - CX88 A/V sync problems in mplayer

I use Leadtek WinFast DTV 1800H to watch analog tv with mplayer on Slackware 14.1 x86_64.
At the beginning A/V sync is ok, but after some time audio comes after video (even 30s and more).

Sometimes I get this in my logs
cx88[0]: irq aud [0x1001] dn_risci1* dn_sync*
Here is my system config:

And my mplayer config:
Anything I can do with this?
