[QUOTE="Maedhros, post: 355690, member: 17242"] Whatisk: I came to that conclusion since I did an extensive search on google using any combination of: video, judder, micro stutter, HTPC, SPDIF, DTS, MKV, MediaPortal, Mediacenter, Reclock, Refresh rate, NTSC.... and maybe a few others. My final conclusion is so far that the judder/"speed up" occurs on NTSC-film/24fps (and maybe PAL/25fps) using SPDIF pass through with DTS. Apparently some of the websites I came across mentioned a bug in DirectSound, which has the unfortunate side-effect that DirectX is not capable of resampling the DTS audio equivalent to the "reverse 3:2" (from 24fps to 30fps to match 60Hz display).... or something like that.... but the result is that my sound goes perfectly, however my video tries to catch up every 20 secs or so (haven't counted seconds though)..... And no, it is NOT my system (I will just update my system specs now, so you can see it). If you are able to, then please try to use WaveOut as your output. However, you will probably get A LOT of stutter and choppy sound and slooooow just like I got. I haven't tried Reclock yet, however they mention potential problems using SPDIF. It is however 50-50 out there it seems. My problems started after a switched from analogue mini-jacks to SPDIF pass through. BTW.... whatisk....
