I'm assuming you mean the "latest" (which really means "recent" ;) SVN

What happens when you apply the attached patch to mythrename.pl?  Note:  
It is not meant as a solution to your problem (thus the name), but 
should help identify if the problem is what I think it may be.  It 
simply disables the "filetype" check (which is currently performed using 

You should be able to apply the patch by going into the directory 
containing mythrename.pl (or a copy of mythrename.pl) and issuing the 

patch -Np1 -i /path/to/mythtv-mythrename_filetype_hack.patch

Note that once the patch is applied all your links will have the ".mpg" 
extension--even those that refer to NUV files.  This is unimportant 
unless you're using the links with a broken OS that relies on filename 
extensions to figure out a file's content type.

If the patch allows mythrename.pl to succeed, please reply with the 
output of:

mplayer -v -v -v -v -nolirc -nojoystick \
        -vo null -ao null -frames 1 \
        -identify '/path/to/radio_recording.mpg' 2>&1 |
  tee ~/mplayer_identify_radio_output

This can be used to "fix" the bindings to work on radio streams.
