wow, this is all great information. i've been looking into removing the audio connection from the headphone jack on the MBpro, but not sure my mini-port to HDMI connection carries audio. i'll have to check when i get home. does the adapter sold by Apple carry audio as well?...because that's the one i have. also, what is the difference between the two dr. bott adapters identified above? they vary greatly in price, but i'm not quite catching the difference between them just from reading the product description. thanks!
