Hi Markus,

The serial of the file in the sheet is 10057. But the encryption is not related to the serial. When I change the original file's serial to something else it still plays fine with foobar.

I can manipulate the whole header except 92-94 and the decryption still works.

It looks like at the end of the AUE file, after the missed change over beep, there is that same pattern that is used to decrypt the file. Could those values be used to add to the file to decrypt it?

I think the pattern at the end is just encrypted silence, so there are only the values for encryption visible. If you delete the second half of an AUE file via HEX editor it still plays fine till the cut.

To me there is nothing more than pos 93 and 94 to decrypt the AUE. 01 @ 92 just indicates the file is encrypted.

Hey Michael,
Can you send me a PM. I have made some progress on the AUE decoder and need some advice.

Thanks,

It happened to me in the mid-1990s, with an entirely forgettable movie called Dante's Peak.
I love that film. The very definition of popcorn entertainment and a throwback to the old-fashioned disaster movie, down to the "no one listens to the scientist who knows better until it's too late" plot line.

I felt Linda Hamilton and Pierce Brosnan had very nice chemistry as a couple as well.
