Hi all,
Sorry for coming back late to report. I did some extensive testing following Matt's suggestions and some of my own:
Wasapi event style with 20ms buffering
Asio with 20ms buffering
VideoClock on and off
Results: nothing improved, and VideoClock ON even worsen the problem.
Note: I don't have any other program running when doing these tests.
Thanks audunth for testing with me on the matter. I concur with
all your findings (except network because I don't have any).
I have to come to the conclusion that this is not a hardware issue, especially with our specs.
I decided to try with videos other than blu-rays and remuxed some from DVDs I have, to see if it only affects very high bitrate videos. For instance, an episode of "The X-Files" DVD with video at ±4,750 Kbps (that's 3-5 times lower than for a BD video) and maximum bitrate ±9,800 Kbps, remuxed to .mkv plays with no jumping hiccups while re-encoded to .ts at <3,000 Kbps bitrate stutters with the jumps.
I believe it's a problem with the specific .ts and .m2ts format decoding and not low or high bitrate resolution. If it were a problem with high bitrate resolution, it would affect the decoding even in the .mkv container too.
@jmone: fingers crossed here
although I currently think it's a video filter issue because I have slightly smoother jumps, although not perfect, with CoreAVC video decoder handling the video decoding while using the Windows Merit Base option with Advanced Direct Show Selection Method.
