Thanks for the instructions to do this people. I must say that this
works quite well.  Tried it for the first time and was able to rip the
audio tracks off the DVD that came with Depeche Mode - Sounds of the
Universe.  

So now I have 3 versions of the album:
A) The CD version.
B) The 5.1 DTS version
C) I also let Audio Extracter create a 2 channel 48khz, 24bit flac
based on the 5.1 dts data.

B & C were both 48khz. 

Some questions:
1) When I did C) I didn't have a way to check (or didn't know) what bit
depth to use when creating the flac so I reckoned use the biggest as at
least I won't throw anything away.  How do I check which I should use?

2) How does Audio Extracter do the 5.1->2channel?  How does it decide
what to keep / how to keep it?

3) Or to put it differently if I had to keep one of A or C which should
I keep (in theory)? I understand that the DTS is lossy compression so
that would tend me to A.  But C has 48khz sampling so that would pull me
to C. 

4) There was a 5.1 AC3 as well but I gather that the DTS is better?  Is
this right? Or is it more subtle than that?

5) I tried the DVD that came with another CD I had and it had LPCM
48khz,16bit (2ch) audio data.  I presume this should in theory be better
than the CD data (as both are lossless but the 48 beets 44)?  Although
in this case the tracks are not exactly the same on the DVD versus the
CD.

Other things I found helpful:
- You can pass "*.dts" instead of the full filename to the script and
it will convert all dts files in the directory.  The instructions was
indicating running it with a specific file name.  
- I found that the .dts files created can be played by VLC directly.

Cheers
Louis
