I went through all of that last year. The only DTS versions of Moment Of Glory on "those sites"
are just m/c rips from the live DVD.
The quality is ok, but even the redbook version of the studio recording of MOG is superior in sound quality to these DVD rips.
If somebody actually knows of a site that has a DTS m/c STUDIO version of the album, you know what to do.
Just so you know, DTS discards 4/5ths of the original data, so the quality is going to be very poor, especially on a high end system. Also the conversion to PCM will degrade the data too. And of course you lose the advantage of DSD as well.
