I used it to set up my 50" Samsung Plasma. It took well over an hour to go through everything, but after watching the whole thing it only took me 10-15 minutes to do the actual setup.
Before the setup I was trying to set up the set by eye. I just couldn't figure out what was wrong. I'd fix one thing and then something else would look bad. After using the DVE setup disc, everything looks great. DEFINITELY worth the money! What's $20 after spending over a $1000 on the TV.
