I got the CD image thanks.
It contains no problems with the encoding of the multi-frame images; further all of the images (formerly JPEG presumably) have been decompressed, since the CD is presumably written to the General Purpose CD Profile, which does not allow compression. The color space had also been transformed to RGB, which means anything can view them, which is nice. There are some ultrasound-specific header attributes that are bad but that is presumably propagated from the original Acuson, and they are relatively harmless.
So obviously the Centricity has good data inside and is capable of processing it "properly" when writing a CD.
Why the other "export" mechanism you described screws up remains a mystery (you should file a bug report about that with your local GE FE, if I didn't already mention that).
As for transferring to Conquest, it would seem expedient to try and find a way to have Conquest refuse the JPEG transfer syntaxes from this source (or at all) ... that would force the Centricity to do the decompression and hopefully color space transformation as well. Since I don't use Conquest, I do not know off hand how to do that, but I am sure there is a way.
