[MPlayer-users] Audio format 0x20776172 is incompatible with '-oac copy'

[vitko]

I use mencoder to join some video clips using

    mencoder file1 file2 ... filen -oac copy -ovc copy -o total.avi

I failed to join some clips (obtained by my Minolta F100 digital camera),
mencoder says

    Audio format 0x20776172 is incompatible with '-oac copy', please try
    '-oac pcm' instead or use '-fafmttag' to override it.

I'm a bit confused - can someone more knowledgeable shed some light on it?

Please see details below.
