There are five kinds of people who need Ovation Software's DVD the AVIA Guide to Home Theater-- (1). It also contains all of the video test. The AVIA DVD will. The Avia Basic System Setup DVD by Ovation Multimedia is an easy-to-use home theater calibration tool containing the core video and audio test signals.
I have the Avia dvd and am happy with it. Another to consider is the Digital Video Essentials disc, I haven't personally used it but have heard it is comparable to the Avia.
The Avia disc has multiple tests with or without explantations to help you better set up your video and audio, including calibrations, test tones, subwoofer sweep, and multiple phasing tests. For me, it made a definate improvement in my system setup. I would recommend purchasing a reputable setup disc and using it for peace of mind and sonic/optical enhancement. Click to expand. Minicons Ultimate Pack. I think some one had posted earlier this year that Avia was coming out with a new version next year that would include audio tests for the surround back (6.1/7.1) channel(s). I don't know if that is true or not. The amount of tests included in the current disc can be overwhelming.
Other than possibly that and maybe some sort of screen wipe (think thats what its called) for plasma burn in, I'm really not sure what else they might add. I bought my disc this year after following the other thread, I have no regrets about not waiting for an 'updated' version. As I mentioned, there are more tests than most people know what to do with on the current disc. I use Digital Video Essential. I find it very useful. There's a complete battery of audio and video tests including Dolby 6.1 sound tests.
It also has tons and tons of information about speaker and sub placement, sound processing, video processing, etc, etc. Very interesting stuff. Three remarks though.: 1- Its more expensive than Avia, about 10-15$ (if i'm not mistaken) 2- It has a bunch of tests with no explications (geared for the pros) 3- The DVD menu is a total pain, never seen worst. I never saw Avia, but I've read a lot about it. If I were to choose again, I might pick up Avia first (if it has 6.1 tests, of course) I definitely recommend you pick it up.
