Well, I looked at your file, and I discovered some interesting things  
about it. First off: the sample you dumped was indeed a RealMedia  
muxed file, not just a stream dump of the audio. However, it's done  
weirdly. MPlayer will play it, but, as you said, seeking is totally  
b0rk'd. It wouldn't give me the proper seek in seconds, but I was  
able to get the percentage to work with -idx (not what you're looking  
for, but it gives us something to start from).

However, when I tried playing it in VLC, it simply started to fill up  
the playlist with gibberish, and spat back enough errors to crash the  
player. I took a stab at it with the RealPlayer (yeah, I have  
that...) but it refused to play the file. It gave a nod to RealAudio  
8, but that's about it. ffplay just locks up when I try to play it.

I also tried my solution: remux it with Matroska. MKVMerge recognizes  
the RealMedia muxing, but it can't find an audio stream. Try as I  
might, I can't get anything out of it. I also tried dumping the raw  
audio data to a file using -dumpaudio. The dump is successful, but  
the binary data is worthless. MPlayer/MEncoder don't recognize it,  
and neither does MKVMerge.

How did you come across this file? Is it a download? A stream dump? I  
think that the problem isn't completely with MPlayer any more, but  
also with the source. Do YOU have any other players that recognize  
the file? As an OS X user, I have a different library of tools  
available (No win32 codecs...) so perhaps you can dig up something I  
can't.
