You see the same thing with those upmix DTS audio CD's which are all over the internet they are all sourced from a stereo track and remixed to a fake DTS track.
As I said in my earlier post it wouldn't be much better due to the source being DD 5.1, but having a faster transfer rate would give it a slight advantage sonically, depending on what kind of data rate you wanted, and it would be more discrete as opposed to Dolby Digital's logic steering. It really depends on your players codecs in the end on wether or not you can actually hear a difference.

I have to dissagree with you on that tellan, my appologies.
I would like to note that I made a mistake on the bit rate of dts at 780 kbps instead of 760 kbps on that last post.
Anyway, it's not so much the compression but rather the Data rate thats the most important factor. The compression is mainly there to account for the bandwith on the media, but it does affect sound quality to a small degree. For example, compressing a DTS track at 760 kbps will not sound much dirrerent at all than Dolby Digital at 430 kbps. Play any movie on dvd that has DD at 480 kbps, and DTS at 760kbps on the same disk, and even though the compression methods a quite different ( DD at 12:1 and DTS at 6:1 ), it's difficult to tell the two apart. You might notice that DTS has a slight edge but not very much. Compressing a DTS track at 1600 kbps ( actually 1.6 mbps in larger terms ) will score you a night for day difference.
If Adywan did decided to convert ( just for the arguments sake ) I highly reccomend the 1600 kbps data rate due to the source material being Dolby Digital, and that faster data rate could very well bring out just a little more in the soundtrack. It might not be much more, but you might be able to tell a difference with good playback codecs.
But anyway, I will still enjoy ADYWANS StarWars no matter how it's presented.
