Page 1 of THX Optimisers - need resetting for each movie???

I`ve got a few dvd`s with THX Ops on them....does each disc have its own
dedicated THX settings or is it a case of set it once and the same settings affect other movies with THX???

I think all of the optimisers are the same.

Think it`s just to make sure that you don`t have the brightness, colour etc. set ridiculously high or low which would obviously have a detrimental effect on the look of the film, and to make sure the levels on your sound system are set correctly.

No, those THX things are disc specific. Mind, I`m not sure how much variation there is.

I doubt changing the settings on your TV for every film are hardly going to make much of a difference?

I used the THX optimiser on the T2 DVD to set up the colour / contrast, etc.... for my TV. I couldn`t imagine altering the screen settings everytime I watched a different film, that would do my head in!!!!

I set my tv using the episode 1 optimiser and then tried all the other ones that I have(episode 2, monsters inc, t2, sleeping beauty) and they were all exactly the same! If there was a difference it was too small to be noticeable.
Don`t forget that THX is a standard so they should all be used to set the same standard!
