MKV saved by Avidemux cannot be used by FFmpeg

[jfx]

Steps to reproduce:
1) Save https://rapidshare.com/files/846234364/fpstest.ts as MKV
2) Use it with FFmpeg: ffmpeg -i fpstest.mkv -c copy fpstest.mp4

This error occurs:
[matroska @ 0x1bf4440] pts (863) < dts (883) in stream 0
av_interleaved_write_frame(): Invalid argument

Yep, confirmed with r8339, but your source file produces error warnings in ffmpeg as well:

Code Select Expand

[h264 @ 0x7fc7bb830400] mmco: unref short failure
    Last message repeated 5 times
[mp3 @ 0x7fc7bb858800] Header missing
[mpegts @ 0x7fc7bb81ae00] PES packet size mismatch

Have you tried other TS or non TS files?
