Because, when programming, you divide the task up into sub-tasks, and since DTS-to-AC3 isn't the only audio conversion possible, the sub-tasks are (among others):

1) Examine MKV file to determine which tracks should be processed
2) Extract these tracks
3) Run the appropriate conversion utility/utilities on the tracks
4) Re-mux them back into the MKV file

The 3rd step may be another program than eac3to - even if doing DTS-to-AC3 conversion, such as DelayCut - so unless ALL the conversion utilities I use can read directly from MKV files, it doesn't make sense (programmatically) to have a special case that says "If doing DTS-to-AC3 conversion on this track, and no DelayCut pass is needed/requested, then do it the single-step way".

No. AFAICS there's no option to eac3to that will allow it to normalize (maximize) the volume by doing a 2-pass conversion, and it'll be too much trouble (programming-wise) to first convert to .WAV files, then maximize volume, then convert to AC3 for something like this.

It's really your TV that is at "fault" here, as the audio level on the DTS track and the AC3 tracks should be identical. My guess is that the 5.1-to-2.0 downconversion done in your TV has an unfortunate side effect of lowering the volume, hence the suggestion to pre-convert it.

Fixed in v1.75.2.

Not that I know of. It seems like WD TV needs some information in the .MKV file that is stripped out when re-muxing the AC3 channel into the file, but AFAIK I preserve all meta information in the file.

Try to run the original file and the converted file through MediaInfo and see if you can spot anything that is removed that you don't expect. Alternatively, publish the output from MediaInfo on the two files here so that we can take a look at them.
