You know to refer to a professional as a pig because they charge money for their services is highly offensive. Why don't you go ask microsoft for the source code for windows in case you don't wan't to buy the next version of windows from microsoft.

Edit:

I don't want to sound like I'm putting anyone down but honestly if you can not afford to pay for Crestron or AMX programming you really don't need the gear. Equipment with rs-232 and ip control cost more then ir only devices. Just because you bought a large screen LCD doesn't mean it will have rs-232 or a cat5 jack. If you don't have either of those forms of discreet communications ports don't bother. Models with these jacks are generally more expensive. If you skimped on the av hardware to be controled it's a moot point.
