What your brother is recommending would work -- however it will only send a video signal from your PC to your TV.

This is the same thing, cheaper for 7.99 but only a 6' cable instead.

You would also need a cable like this one http://www.tigerdirect.ca/applicatio...5581&CatId=449 (plug into your headphone jack on your PC and will split into left/right channels so you can have stereo audio instead of just mono -- plug into the TV - $16)

That setup would run you around $24, +tax +shipping, unless you source it locally like at Radio Shack or such.
