Finally preparing the source HDV.M2T MPEG-2 media in a blu-ray M2TS format format with E-AC3 audio.


ffmpeg -i 20081103140154.m2t -c:a eac3 -c:v copy 20081103140154_m2t-eac3.m2ts

ffmpeg -i 20081103140154_m2t-eac3.m2ts 2>&1 >/dev/null | egrep "Audio|Video"

  Stream #0:0[0x1011]: Video: mpeg2video (Main) ([2][0][0][0] / 0x0002), yuv420p(tv, bt709, top first), 1440x1080 [SAR 4:3 DAR 16:9], 25000 kb/s, 25 fps, 25 tbr, 90k tbn, 50 tbc
  Stream #0:1[0x1100]: Audio: eac3 (EAC3 / 0x33434145), 48000 Hz, stereo, fltp, 192 kb/s
