Hi,
I have the AVIA disk and had never calibrated a TV before. I found it very straight forward and found the commmentaries and explanations quite usable. I took some notes while I listened, it made it easier to remember what it was I was supposed to be looking for on each of the test screens while adjusting the different settings. It has a lot of good knowledge for the beginner and has a 100 other tests that are for professionals (I assume).
The end result was my TV looked considerably better than when I first took it out of the box. I continue to tweak it a little but at least now, I possess the scary bit of knowledge needed to really make a mess of things!
I would recommend the disk.
Regards,
Dave
PS the sound set up and test tones are also very useful for HT.
