maybe an upload error or who knows what.

I hope not, considering I was the uploader back in '06 :)
Actually I have received that file twice on discs Belbucus sent me. First in Fall '06 then again in Summer '07 when mono restoration was finished. The two discs are different brands with different dye recipes. It's the same file on both discs: same timestamp and same CRC, which I've quoted above.
(And the file posted to usenet ~400 days ago has the same CRC as well.)
So I'm quite confident saying it left Belbucus' studio that way.
Belbucus is a pro, and a human pro at that.

Now this reminds me ... there exist two distinct versions of the ANH file "DC48 DVD.wav" which have different CRC.
I shall pinpoint where the difference(s) occur so we can all have a closer listen....
