Alright so I'm finally ready to take the plunge and expand the capabilities of my beloved iTunes streaming/rental box. I consider myself somewhat tech savvy, but all the googling I've done seems to assume I've already hacked the thing and am hip to the basics. Obviously I'm a noob in that regard and just would like to know where to start. Where can I find tutorials for a beginner and what are some suggestions on the best software to install? Thanks much for all your advice.
