I am just wanting to know how I can get the clearest picture playing a DVD movie through my Xbox. Is there any ways to play a DVD movie in 1080i??

I have my Xbox hooked up with component video cables to my TV and also just bought a 52" LCD widescreen today.

Please let me know the best way to play a DVD movie using this setup. Thanks!!

You dont want 1080i for your tv, since a high def LCD's native res
will be fixed at either 720p or 768p. Set your xbox dash to 720p, if your set is
fixed 720p you will get a 1 to 1 pixel map and suffer no scaling artifacts
and get a better looking picture overall.

This TV is not actually a LCD TV it is a Rear projection TV. I screwed up the other day when typing the thread (was in a big hurry). This is what it actually is:

JVC 52" Widescreen HD-Ready Rear-Projection TV D-ILA w/HDMI Input

Here is the link to best buy for this TV:

So 720p is actually better than 1080i? If so then lets say that I set up Avalaunch in 720p on my xbox and then start up DVDx to play a DVD. Then the DVD will actually play the standard way that it does wouldn't it?

One other thing is that when I do enable 720p in Avaluanch it looks worse then what it does when I set Avalaunch to use 1080i. I dont understand this.

Still, the native resolution of your TV is 1280x720, so it never makes sense to scale above 720p as the TV will just have to scale it back down.  So for your TV, 720p is going to give you the best picture.

I've looked into it some and am unconvinced that most displays will 1:1 pixel map unless the overscan is handled optically.  This means to me, LCD flat pannels are out of luck unless you set it for zero overscan (which then affects the rest of your programming unless the service menu is really designed to allow for this and most aren't).  For a flat pannel LCD, if there are 1280x720 viewable pixels that means a general HD signal in 1280x720 is getting cropped at the edges for overscan and then rescaled back to the viewable pixels killing any 1:1.  Same for plasma displays.  Personally, scaling an HD signal is generally fine by my eyes but 1:1 mapping seems to be prohibited by overscan settings.

[Mr Ed]

If you have an HD signal (i.e. 720p or 1080i) and an LCD or DLP type display technology, then overscan actually doesn't make any sense.

Are you sure these types of TVs have overscan at these resolutions?

[project722]

Yes they may have overscan, it depends on the tv and the signals coming in. HD fixed pixel devices are capable of eliminating overscan and providing a true 1:1 pixel map, but other displays cant(CRTS), so even high def programming producers still produce images for the "sweet spot" or "safe zone", knowing the recieved image will be overscanned by the tv. (damn backwards compatibility thing   ) Some fixed pixel
HD sets now have a setting for TV or PC, where the PC setting will give a true 1:1 pixel map with no overscan. This would be great for high def xbox signals as I assume that  every line contains actually usefull data.

So what resolution should I run my XBOX at with the display on my plasma tv. My TV has a resolution of 1024 X 768. I have it set to 1080 and DVD's look great. Wouldn't it be better at 1080 scaled down to 768 instead of 720 scaled up to 768?

My plasma TV

[project722]

Of course it look great its a plasma.   But sending your set a 1080 interlaced image will have to be de-interlaced AND scaled down to 768p. Your set is natively progressive, not interlaced, so set your xbox to the closest progressive resolution, which would be 720p.

Yea it bites I know. And with digital broadcast images, theres less crap around the edges, so the more oversacn a set has the more image thats hidden. I hear the new sammy HLP series DLP's are capable of a 1:1 pixel map and only 1 to 2% overscan.

[FallsInc]

will the forthcoming 1080P tvs be 1920x1080 at native res?

[project722]

Yes they will. All HD incoming signals, and most others, will be able to be displayed at 1080p, without the data loss that occurs when format converting 720p>1080i and 1080i>720p.

Overscan really has nothing to do with pixel mapping. Fixed pixels devices give you 1:1, even with overscan, like you said just some of the pixels are hidden from view. But even in digital broadcast television, there will always need to be a some overscan, as some active lines dont actually contain image.
