xbox, how to get good picture on LCD tv ???

I have just got a new LCD television and want to know to get the best results out of my xbox. (not 360,,,,,,,,,,,,yet)

I have been using a old 28" BUSH tv, which to be honest, when using the RGB scart cable looked bloody amazing!

Now I have switched to my new LCD and the picture looks bad in comparison. Half life 2 looks fuzzy and now I can not even see the badies in the distance that I could pick off with ease when using the old tv.

I know the problem is not the tv as it looks good using my dvd player. i realise that LCD's are so sharp they actualy highlight the bad pictures that normal tv's blur out, but I'm sure this should be capable of a better picture.

I am using the advanced AV pack (RGB scart) which I realise does not support HDTV. I have read other forums that advise people to get a VGA box but they were talking about using a computer monitir rather than a LCD tv, does that still apply, should I be using the VGA input???

If there is anybody out there getting a nice sharp picture on a LCD, please tell me how you are connecting it and what settings to use etc!

specs etc.....

It's a Prima LC-27M7S
It's 27" and has a native resolution of 1280 x 768.
It supports 1080i/720p/480p (no 1080p I'm afraid but I challenge anybody to find a better tv for less than £500!)

It's got all the usual inputs, S-Vid, RGB Scart, Component, VGA and DVI.

I have the normal red,white,yellow output and the av pack with RGB scart. By the way, even though the scart kicks ass on my old tv, the crappy red,white,yellow cable actualy seems to look better on my LCD, figure that one out!

Since posting the above I have been told that it is common for the xbox (or PS2 for that matter) to look pretty damn rubbish on even the most expensive LCD screens when using 'old' type connections such as S-vid or even RGB scart.

I have had a look round and found an 'xbox HD AV pack' which has Component (red, green, blue) output sockets which according to some websites will do the trick.

If anybody has used one of these could you drop a few lines to say what it's like?

ONE MORE QUESTION, Do the Video options available on the xbox change when you connect this AV pack? People are saying "use the HD pack and switch to 480p" etc etc, but there is no such option in my xbox settings. So what I was assuming is that the option will appear when you connect the HD AV pack.

Is that true?
