view tv with audio from radio channel

[leo at calidae.net (Leo Márquez)]

Hi all,

Somebody knows if it is possible what I say? 
That is to say, to see a channel of tv but with the audio of a radio 
channel. 
One is implied that the channel of radio and tv are in different 
trasponder or the system have sufficient cards.
Perhaps exists a plugin to do this?

Thanks
