So I gave this a shot, works fine on shows recorded off of my hdpvr,
but not recorded from qam on an pchd5500:
Use of uninitialized value in pack at modules/stream/stream_flv.pl line 103

Seems like it can't get the duration from that ffmpeg:

Seems stream 0 codec frame rate differs from container frame rate:
59.94 (60000/1001) -> 29.97 (30000/1001)
Input #0, mpegts, from '/tv/5111_20100217195900.mpg':
  Duration: N/A, start: 81708.981356, bitrate: N/A
  Program 1
    Stream #0.0[0x7c0]: Video: mpeg2video, yuv420p, 1920x1080 [PAR 1:1
DAR 16:9], 38810 kb/s, 29.97 tbr, 90k tbn, 59.94 tbc
    Stream #0.1[0x7c1]: Audio: ac3, 48000 Hz, 5.1, s16, 384 kb/s
    Stream #0.2[0x7c2]: Audio: ac3, 48000 Hz, stereo, s16, 192 kb/s
