setting up settings

[radcast2]

I used the THX Optimizer (located on Star Wars Episode 2) on ly LCD HDTV, the picture quality form my 360 has a HUGE improvment. My question is this...I set that up using a 720p output of the 360. I was told that I most likely have improved my PQ by about 60% but it could be even better if using a digital setup disk like the ones found here on the FAQ section.
My digital cable converter is hooked upto the TV by composite video cable, I was wondering if it would make sense to run the optimizer on a non-progressive scan DVD player using the composite videos cable to set the PQ up on the digital converter or just set it till I feel the picture is clear. Or should I get e VCR tape, copy the DVD set up disk to a tape and run it that way?

Each of my inputs allows for different settings.
I have Digital Video Essentials DVD coming in next week, so I am just trying to get a jump on things.

I would suggest you wait for DVE and use it to set up as many inputs as you actually use. For the others, you may simply wish to "copy" the settings over and adjust by eye for now.
