Last night "the bug" hit me and I went to Best Buy to get a calibration DVD. The first salesperson in the HT department never heard of one. The 2nd did and pointed me to the special interest DVD area. They had only one type called "Home Theatre TEst and Set-Up Disc" for $9.99. Well - I had "the bug" so I bit the bullet and bought it. It's totally worthless. Actually worse. My wife and I tried to tune our 27in Wega Trinatron 3 times and all three times the picture turned out unwatchable. The Audia section basically tests if the speakers are actually connected to the receiver. that's all. In this case you get less then what you pay for.
