Hackney,
The Avia test dvd is a top notch audio/video calibration device for home theatre. IMHO it is a must have for the serious installer/tech head or homeowner that is interested in their technology. It will DEFINATLY make your system sound and look MUCH better than it does now! Actually, the video tweaks are extremely easy to learn and master and will have your TV looking like film instead of video in about 1 hour of tweaking time.
Get it now and don't delay, it's the best 30 bucks I've ever spent. Get it at amazon.com or go to
