HDTV / progressive scan question

Ok I am still very new to the HDTV/RPCRT scene - so please be gentle.

I have a Hitachi 51s500. Just recently bought a Sony DVP-NS725P DVD player. My previous dvd player did not have progressive scan on it. I was hoping that the progressive scan on the new Sony would make some difference in picture quality. I have been trying to see it along with my roomates - but we don't really see a difference. I have the tv set to 1080i.
I hooked up the dvd player using s-video.

Am I doing something wrong? Or is the difference with progressive scan very subtle?

Thanks for the help
 
You MUST hook the DVD player up using component video connections in order to take any advantage of progressive scan capabilities.

So s-video would actually make it worse?

mmm....DVI

The Samsung has DVI and automatically upconverts to 1080 🙂

I am seriously debating between that and the Toshiba DVD/Tivo unit
 
So...according to this picture, input 3 is fine? Whats the difference with input 2?

Component is just the red,white and yellow cables that normally come with lots of a/v equipment right?
 
The red white and yellow cables that usually come with a/v equipment are for left channel/right channel and video (composite video).

To use the component, use Input 1 or Input 2. The PR/PB/Y inputs is for component video.
 
component breaks down video to red/blue/green. Use input two, that way if you get a HD satelite receiver you wont have to move things around.

Ok one more question - can I use composite cables for the component inputs?

Thanks btw - i love the tv 🙂

you can try. But you would be defeating the whole purpose of component. Go spend the $30-$60 for a decent set and you wont be disapointed.

Technically component video breaks the signal down into a luminance signal (Y) and two chrominance signals (Pb and Pr) which serve to send colour information for red and blue.

Edit:I think that both composite and component video cables are supposed to have a 75 ohm impedance so it should work in theory. In practice the majority of composite cables are very cheap and probably won't be anywhere near as good as quality component cables.

It depends on the quality of your RCA cables (try and see if it works) but to make the picture look as good as possible you need to get a component cable designed for prograssive scan video.

LOL...its ok, it was the salesman in me trying to dumb things down. I spend my day trying to teach 75 year old people the difference between 720 and 1080. I tend to get lazy sometimes.

Can somebody please explain to me why people say SPDIF coax is better than SPDIF optical? Digital is digital, as long as there are no errors in the data transmission I could send it by telegraph or by pigeon if I wanted and it should work in exactly the same way.

Someone please explain this to me, I'm dying to understand what this is based on.
