[MPlayer-users] alac file: invalid ALAC magic cookie

[andrew]

Hi,

I notice that MPlayer cannot play files produced with Apple's newly
released alacconvert utility. The error message is as follows:

I was unable to transfer a file to the MPlayer ftp site so I have
placed my sample file here:

Thanks for looking at this issue,

Andrew
