Hi Ronald, the symptom is an incorrect AVStream.r_frame_rate value, often in
the kilo-frames-per-second range.

As bit of background, the wtv file format sometimes provides PTS values.
Many packets output by the demuxer have no PTS.

Example: 'Gilmore Girls_Net 5_2011_01_08_16_10_53.wtv'
Stream #0.1[0x26]: Video: mpeg2video, yuv420p, 720x576 [PAR 16:15 DAR 4:3], 10000 kb/s, 25 fps, 5000k tbr, 10000k tbn, 50 tbc
                                                                                                ^^^^^^^^^ wrong
gilmore-read_packet.txt, lists the AVPackets that the demuxer outputs.
    The pts values occur prior to parsing As you can see, packets with valid
    pts are infrequent.

gilmore-av_read_frame.txt, lists the AVPackets reterned by av_read_frame()
    This occurs after parsing. The first few packets have different delta-dts
    values to the remaining. This causes duration_gcd (within av_find_stream_info)
    to blow out and thus r_frame_rate=5000000.

1_2_englush*.txt is another example, where tbr is 1k

An alternate fix is to increase the number of frames used to calculate
r_frame_rate. The enclosed patch fixes all (three) of my broken samples.
