Strange Video Pause After Being Remuxed

[x0pht]

Could anyone please analyze the following file and find out why the video pauses for half a second at 00:00:04?

it's a short m2ts file sample (23mb), the original m2ts source is good. I tried both tsmuxer and eac3to, same result. When I played the file frame by frame, it was good.

if it plays fine on your computer, please also let me know.

Thanks in advance!

No hickups here with Haali 1.9.42.1 as splitter and DiAVC 1.2.6 as decoder.
CPU load (C2D T7600G @ 2.33 GHz) around 50%.
The bitrate peak is around 27Mbps (nothing serious for Blu-ray) @ 4s.
What CPU and which decoder do you use ?

It happened to me. I have no idea as to what it happens. Try to remux it again but to a different hard drive.

Thank you both for the replies.

Emulgator, im using ffdshow x64 and haali 1.10.348.15. CPU: C2D E6400 2.13GHz. The pause happened on both MPC-HC and windows media player (WMP uses its internal decoder).

Pako, i've tried. actually the issue came to my attention when the file was in a mkv container being played on a different HDD. The pause is always there as long as the original file gets remuxed, regardless of format/container, HDD, tools/playback software being used, etc. But the original file plays fine on my computer. and also, someone else tried to remux the same source, it turned out to be fine (which means their output file plays fine on both their computer and mine).

So there must be something that went wrong during the remux, but i dont understand what went wrong, and I also dont understand why both tsmuxer and eac3to output the files with the same issue.

EDIT: could someone please explain to me in details how demuxing works? do all or any of those demuxers need to access certain common files to do the job?
