i want to stream my media wirelessly to my TV or stereo

i have a macbook a few years old running OSX 10.5.8
the Bluetooth software version is 2.1.9f10
both my TV and stereo have RCA inputs

1. i'd like to stream my media wirelessly from my macbook to my TV (music and video)

OR

2. i'd like to stream just my music wirelessly to my stereo system.

i'm under the impression i will need an Apple AirportExpress to do the first option... but i'd rather not spend that much.

is it possible to do this via Bluetooth with just my music for a much cheaper option?

does my macbook even have stereo bluetooth?

i'd prefer some advice on the cheapest options for both scenarios.

any help is greatly appreciated.

cheers.

would that work as a cheap solution for scenario #2?

have it plugged into the wall next to my stereo... pair it to my macbook... and have a headphone jack -> RCA cable coming out of the device into the back of my stereo.

would i be able to play music through itunes just like normal on my laptop and have it play through my stereo speakers?

AppleTV, dude. AppleTV.

I'm with chas, this is the exact need that the AppleTV was created to satisfy.

There is the Motorola dc800

I found one in the bargain basement bin at my local Best Buy for $15.

I dunno - at ~$50 I would pay the extra for the Airport Express and pay some extra money for Rouge Amoeba's Airfoil.

I've found that a2dp becomes a pretty intensive app to run. Stuff stutters a lot more than I like.

I am unconvinced about Apple TV. At $230 - I'd rather spend my money on a Mac Mini. Personally at $700 it isn't that much more expensive - or you could find a used Mac Mini for close to the same price and get much more functionality.
