Someone previously stated that you have to go through 1-1,5 hrs of boring voice which is not true. The voice is not the best they could have picked but what it talks about brings you closer to understanding what HD is all about. I doesn't take 5 mins to tune up your TV as it takes about 3 hrs for a professional who'll take £250 for it and this helps you do it yourself. I've bough mine some time ago from USA and believe me it does magic to your TV. You have countless pluges on DVD that'll help you set your picture to the best possible level without getting into service mode. It clearly explains the risks of running your TV on the torch mode (everything set to max) and tells you what to avoid when using your set. When I bought my new Sony 40'' LCD it was horrible to look at but when I plugged the PS3 and tuned it with this DVD the difference is so vast that you will not believe your eyes. I think that £15 is money well spent as it will help you maintain your TV in good condition for a long long time.
