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.
