Not a comparison, but you can see an HD image on the front page of my website, in 1080i on my 65" Panny. It's not sports, but I think you'll see the incredible difference between it and ANY analog pic you could possibly imagine.
Just click on my website below, it's a pic taken in my living room. It is actually a closeup of my bigscreen - an analog 35mm photograph of my TV, with an HD pic from CSI showing on it.
The negative was scanned with scanner that does that, and the result sent in to the website - you can see the indicator lights of my AV receiver above the TV's image.
If you go inside the website to the Screenshots page, you'll see a Before and After of a ceiling projector, before and after convergence. I have other Before and Afters, but they are not up there yet.
Erik,
If you don't mind, could you email those pics to me? [email protected] When ever you get a chance. Thanks. I will put them on my online photo album and post them back in this thread.
