Real mess in HD, need explanation!!

[joweyx]

Ok, I would like somebody to clear my dubts in HD.

First, let me tell you what i have in order you understand. My computer has a 8800gst wich is necesary to display BD and HD-DVD right? But i heard if a movie is displayed tru VGA, HDCP is useless? :heh: Can I still play in HD? I have a monitor Dell 2007FP wich is no listed as HDCP, So i can´t play HD?:frown:
Besides this, i have a Samsung TV and BD, HD-DVD movies. My TV can display 480i, 480P, 720i, 720P, and 1080i. This are my final questions:

-Is a movie made in a especific resolution?.. and so.... how can i know this.?

-Let me put an example, If I have a movie at 720, does my TV can display it only at 720 or it "will" upscale it to 1080?

-What is "ATSC"?

-Is VGA better than composite?

-It Widescreen really necesary to apreciate HD?...Or can i do that on my actual monitor?

a 8800gts isnt necessary to display HD, i think the 7600GT and the x1650 are the minimum cards that support HD

A good processor will take most of the brunt of HD decoding but if you have a graphics card with dedicated HD-decoding hardware on it you'll do better.

VGA does not support HDCP, HDMI connectors are needed for that.

Movies are displayed at their normal resolution in a software decoder such as Power DVD, it will show it as 100% size unless you fullscreen it. If you mean recorded on set, the no; movies are recorded onto film which has a resolution greater than any monitor as it is not a digital lossy format.

Depends on how it is set. Read the manual, search AV forums for threads about your model. Odds are you can choose to view it at 720p or have it upscaled to 1080i (HD stuff isn't really my forté...).

If by composite you mean component, then no, component is considered to be able to transmit with higher quality than VGA and can transmit unprotected HD content.

Most HD-TVs are widescreen. Your monitor is widescreen (iirc) so no worries.
