While playing different HD channels i noticed that sometimes the picture starts stuttering, seems like A/V out of sync or else and mplayer starts skipping video frames. Quick pause/pause fixes playback but over time it starts stutter again. With cache 8192 it is significantly better,  stuttering happens rare now.

I remember some pretty old post about A/V sync problem and cache not being catch up or something, so my attempts to play with cache size

hmm, did you try adding -cache-min 99 ?
otherwise if its from dvb only that would be very hard to diagnose. not
to mention adding vdpau in the mix.
