[Cin] Testing HDV on a Blu-ray Disc Without Re-encoding

[Terje J. Hanssen]

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

Trying to follow the manual's 7 procedure steps to create the Blu-ray 
structure and burn it to a DVD+RW disc (with root access):
# My comments and questions included.
