Wireless TV tuner to send to bluetooteh module OR AirPort Extreme

Hello,

This is what i’m looking at doing. I want a device that will connect to my TV and send wirelessly to my Imac G5 (to the bluetooteh module OR AirPort Extreme) so that my Imac can record it.

This is so that i can have my TV in the lounge room and still be able to record TV on my Imac in my computer room (5 - 10 metres away).

just to double check you get what i mean. There will be no external attachments to the actual computer, just on the TV which sends to the bluetooteh module OR AirPort Extreme already inside.

doesn’t anyone know a device like this?

THANKS!
