Wrong duration of mpeg-ps file

[zoominla]

Reproduce command: ffmpeg.exe -i test.mpg
FFmpeg version: current
Output of ffmpeg:
[mpeg @ 01BF9760] max_analyze_duration 5000000 reached at 5016000
Input #0, mpeg, from 'F:\video\mtv\F0155301553685.mpg':

Duration: 22:19:26.97, start: 0.213000, bitrate: 14 kb/s

Stream #0:0[0x1c0]: Audio: mp2, 48000 Hz, stereo, s16, 256 kb/s
Stream #0:1[0x1c1]: Audio: mp2, 48000 Hz, stereo, s16, 256 kb/s
Stream #0:2[0x1e0]: Video: mpeg2video (Main), yuv420p, 720x480 [SAR 8:9 DAR

4:3], 4000 kb/s, 29.97 fps, 29.97 tbr, 90k tbn, 59.94 tbc
At least one output file must be specified

Problem: ffmpeg detected duration is 22:19:26.97, in fact it's 4min 17s. Mediainfo and players(VLC) detect it correctly.

Please add the complete, uncut console output and please provide a sample.

Sample uploaded to ​http://samples.ffmpeg.org/ffmpeg-bugs/trac/ticket2018/
Duration is detected correctly if the last 4k are cut from the sample, this does not change the output of -f framecrc.
