Surround Sound Bug

When playing some test files for testing surround system I noticed that some of the channel is reversed, and with different format the reversal is not the same

1st file: http://www.phoenixdigital.com/surround/surround-7-1-test.flac (Right surround, right surround rear, and left surround rear are wrong; left surround is not being played at all)
2nd file: http://www.phoenixdigital.com/surround/surround-7-1-test.wav (Right surround rear and left surround are wrong and I think left surround rear is not being played at all)

Thanks

I will do some tests.

Btw, I tested this on stereo setup to try surround emulation

I get the same behavior with three different decoders, so I am pretty sure there is something wrong with these files. Do you have any files from a different source that play incorrectly.

I see. I just assumed that because these are test files then they should be correct. Unfortunately I don't have any other file to test.

Thanks for testing though
