 Frameratedetection does not work well on some of my files:

 ffmpeg -i wrong_framerate.mkv:
 [matroska,webm @ 0x276e420] Estimating duration from bitrate, this may be
 inaccurate
 Input #0, matroska,webm, from 'wrong_framerate.mkv':
   Duration: 01:47:42.18, start: 0.000000, bitrate: 1984 kb/s
     Stream #0.0: Video: vc1 (Advanced), yuv420p, 1920x1080 [PAR 1:1 DAR
 16:9], 29.97 fps, 29.97 tbr, 1k tbn, 29.97 tbc (default)
     Stream #0.1: Audio: eac3, 48000 Hz, 5.1, s16, 1536 kb/s (default)
     Stream #0.2: Audio: eac3, 48000 Hz, 5.1, s16, 448 kb/s
 At least one output file must be specified

 ffmpeg version: git-N-30444-geb5a3ab
 correct framerate: 23.98/24 fps
 same false framerate detection with latest VLC
 xbmc does play it with the correct framerate and does play it without
 problems.
