[QUOTE="dm15644, post: 103354"] Hi everybody, I figured that the jitter is minimized when I put the PCI latency for the video card to 0 and for the TV card to 255 (the maximum). It's still there, but it's only one or two frames that are hanging. Most interestingly, the jitter is completely gone when I manually deactivate EPG over DVB-T for all channels in Settings/TV/DVT-T EPG. Usually, my system comes to a short halt when the TV card is switched on in the TV menu. Is the TV card switched on an off when grabbing the EPG from DVB-T? If yes, then this would explain the last bit of stutter. And if so, is there a way to control the EPG-over-DVB-T grabber, e.g. in such a way that it's doesn't work in the background? Or, alternatively, that it's activated eg. only once per day? I think I can live with one stutter event per day...... Cheers /jayorck [/QUOTE]
