ID 20: Group 1 (Lf, Rf, Ls, Rs), Group 2 (C, LFE)

and they are all valid channel order for 5.1 MLP, decoded to WAV, they all produce the same WAV file with the valid channel order for 5.1 WAV files: Lf, Rf, C, LFE, Ls, Rs.

I know that there are multiple channel ordering variations for MLP which are all "correct". I didn't know the details, though.

I know. I just wanted to post something other than "5.1" to indicate that this is not the normal 5.1 channel order, but something different. I didn't expect that this other ordering would really be used in real life, so I just named it "wrong order" just to give it a name.

3) with -libav switch all of the above samples produce:

and no output at all, i don't know why because i have ffmpeg patched with one of the first MLP patches and it decodes all of the samples without complaining about the checksums, so maybe with the newest ffmpeg MLP patches, something is broken and previous versions are better to use at the moment, because there is no problem with the checksums according to Surecode MLP:

here are the samples: http://xkodi.svobodno.com/mlp51/

Thanks for the samples! Will check this out. May take a few days, though.
