When burning BD content on standard red laser disc I select Disc type: AVCHD and Image type: BDMV (AVC)
The default Best Quality setting equals a max. bitrate of
17,000kbits/sec and a max. project lenght of 35 mins with DD5.1 or 36
mins with DD2ch.
The lowest possible bitrate setting S12 is going to accept is 13,000kbits/sec or 46 mins on disc.
In order to write 40 mins on a standard DVD the bitrate is to be set at 15,000kbits/sec.
When using a double layer 8.5gb DVD the project lenghts mentioned above can be multiplied by 1.8.
35 becomes 63, 46 becomes 83 and 40 becomes 72
