Hi,  I have exactly the same problem and have been having for many 
months.  For me it's much worse, it happens for every video file  that 
get_iplayer downloads,  when playing them back on the PS3 via a media 
streaming server the video plays at approx 2x and I get no sound or 
static.   I have worked round this problem by using 
http://code.google.com/p/ps3mediaserver/ which has an option to 
transcode the file using MEncoder which it does on the fly as it streams 
the video to the PS3, it then plays fine.    The disadvantage of this is 
that it's slow to start playing and you can't fast forward or rewind the 
video.

I tried upgrading my version of ffmpeg to see if that would fix it but 
that didn't help.   The files play back perfectly on the PC so I don't 
know what's wrong.

If anyone has any suggestions for things that I could try out to 
determine what the problem is, I'd like to hear them.

Thanks,

Michael
