The problem appears on a variety of DVB-T devices, with or without hardware accelaration on the LAV decoder at all (I don't use Intel Quicksync, the internal gpu is completely disabled).
Have you actually tried DVB-T decoding with SVP? I suspect it's a universal issue. Since I've been having it on 3 different devices on 2 different PCs.
The choppiness is basically like the video is smooth for 1.5seconds but then it completely goes still for 0.5 seconds, or something like that.
edit: I repeat that the problem is NOT there if the raw stream is first recorded in VLC and then played back on SVP/mpc-hc so it's definitely something that occurs only on live playback and it's not related to hardware speed since the hardware is new and it can play much heavier videos anyway. It's of course not there if SVP is disabled also. Anyone else with the same issue please reply.
