DTS is indeed optional - all DVDs are supposed to carry an AC3 version of any
audio track, to support players that don't handle DTS.

The PCM they talk about is 'DVD LPCM'. We have the 'dvdlpcmdec' decoder element
for it, but not an 'encoder' (even though the encoding is just byte
rearrangement). I'm not sure what FFmpeg has for encoding the correct LPCM
format. A quick glance suggests they might only support encoding 16-bit LPCM in
the muxer (I can only see references to CODEC_ID_PCM_S16BE in the code) 

DVD LPCM is used mainly for (for example) music concerts, where sound fidelity
is important.
