[QUOTE="Spooky, post: 274278, member: 11539"] I did some further testing. I let the TV server make a recording of ORF 1 HD a few minutes. After that I played that recording via Media Portal and everything was fine. Video played smoothly at 50 FPS everytime I tried it (except a few seconds in the beginning). Playing the TS file via Media Player Classic (Home Cinema) through the same PowerDVD codec also works just fine. I also tried letting the TV Server buffer the stream for a minute or so (by hitting pause) and then play it, but that didn't help, still only 33 FPS. Initially I thought this might be a problem somewhere in the Codec -> VMR9 -> Driver -> Hardware pipeline, but maybe it's a problem in the Source Filter? Since the recording works fine, but direct viewing not. I also experienced a drop to back 33 FPS on ORF 1 HD on my own system (with CoreAVC, where it usually works with 50 FPS all the time) after pausing the stream. [/QUOTE]
