i'm looking to buy my first receiver very soon. i'm looking to spend 200 or less on one. what features should i be looking for? i have a decent speaker system its not the best but for my small room its perfect. i may upgrade the speakers later on but at the moment its not really necessary. also what exactly does the receiver control? i know the control audio yes, but i've seen receivers with video inputs and outputs on them. does that mean i will be able to say connect my dvd player, vcr and tv all up to the receiver and not have to switch between them all, but the receiver will do it for me? sorry if these questions are basic i'm just getting into this and really could use all the guidance i can get. thanks alot guys!!!
