I did a little oops here...I tried to load a custom matrix but I clicked on the zipped file with the matrices...apparently this function isn't very bright, so if I'm neither then your custom matrix will look something like this:

I don't even want to try to think of how the result would look like. :D :D
Anyway I understand now how to make screenshots so that's a good thing. :)

Lol, that 80 in the upper left probably will screw it up the most :).

Thanks for the jokes - now for some more serious help:
Somehow it looks like you loaded not a custom quantization matrix, but anything else. A matrix file will be 128 bytes (2* 8x8), and the top-left intra parameter shall always be 8.
Although most matrix files unfortunately have a file extension *.txt, they are not readable text files, but instead binary files.
Dear XviD developers: I strongly would recommend to use a specific filename extension -- for example: "*.cqm" (Custom Quantization Matrix), or "*.qmatrix" (just like ffvfw does)!

LOL..i didn't expect anyone to consider this a plea for help. :D
Really I know what I did wrong. That's why it's an 'oops!'.
But I wouldn't mind if an extension could be found for custom matrices. You just have to find one that's not in use preferably.
Others could be .xcq for XviD Custom Matrix or similar.

Grmbl... I just missed that you don't ask for help, but wanted us to enjoy your mistake; sometimes I'm just too eager to help... ;)

Indeed, I already used "*.xcm" for some time now.

Furthermore: The file extension ".txt" makes some servers tell a MIME type "text/plain", and this makes clients (e.g. web servers) believe that the file was sent in ASCII mode. This means: If the file contains bytes with a value 13h, a Windows FTP/HTTP client appends a byte with value 10h to match the line break rules - this makes the file larger and destroys the matrix this way! Now imagine Acaila's matrix...
