I have read and plan to follow the advice that was in the insightful post titled "itunes with external hard drive instead of internal hard drive." In addition to running iTunes from an external hard drive on my iMac I would also like to run iTunes, from the same external hard drive, in my living room (with some set-up using the TV as the monitor). I'm not sure exactly how to do this. I'm assuming I need to set up more of a server to serve multiple locations. And, I'm hoping all the smart people that read this can offer some sort of assistance. The end goal would be that I could listen to iTunes (music I want to listen to) on my Mac in my office and my wife could be listening to iTunes (music that she wants to listen to) in the living room. Ideally the setup in the living room would be one in which I could change the TV input from DVR, to DVD, to iTunes, so that the iTunes input on the TV would like the iTunes program on my computer (and that would be the only possible program from that input setting). I hope my end goal is clear enough and I thank anyone who responds with viable solutions.
