I envisage that a mono WAV (or perhaps encoded to a losslessly compressed format) will be made available to those who want it.

For the end user however, I would advocate the use of Dolby Digital (AC-3) format, because:

- mono PCM is not a legal audio format for DVD

- "dual mono" 2-channel PCM takes up an excessive amount of space which could be better used for the video encode

- with AC-3, the video could be left untouched if desired (on a dual-layer DVD)

- "dual mono" PCM - or MP2 for that matter - would play out of a surround system through both the front left and front right speakers (unless some form of processing is applied at the receiver) which tends to sound "remote" from the action on the screen

- AC-3 1.0 would correctly play out of the centre speaker only
