7.1 FLAC to Vorbis --> Channel mapping ist totally messed up Options

[McKebapp]

Hi Gals and Guys,

I'm a little lost. I try to encode a 7.1 FLAC File to a 7.1 Vorbis File.
For some strange kind of reason, the mapping of the encoded file is totally messed up.
Front Right is on Center, Right Side on LFE, Right Rear ist Left Rear and so on.

I don't know what I'm doing wrong.

For encoding I use the command line encoder "Oggenc2.87 using aoTuVb6.03".
My settings are: c:\vorbis\oggenc2 -k -m160 -q8 71file.flac.
The resulting 71file.oga plays nicely and is very small. But the channels...

Is there any attribute I can set to prevent a remapping? Or any to force a remapping in a particular order?

I'm sorry, I've been searching this forum for hours, but I didn't find anything useful

Thanks in advance,

McK
