in Nokia n8 there is FM transmitter. You can play HD videos through HDMI to DVI and output the audio using FM transmitter.i haven't tried this on my n8 though
Cool lagi na. Transmit niya ang audio through FM. Murag advanced ra sad kaayo. hehehe
Update:
I used an RCA to 3.5 mm converter and it is working great. I don't have to use my TV Box anymore for the audio.
All I do is connect the red and white component cable and my speaker to the converter.
