This is a continuation of a thread several folk were participating on with regard to whether there is any extra detail to be realised from scaling to higher res panels than the native res of the source.
I will try to dig out the JoeKane article I mentioned but in the meantime I give you this email I was sent today. I have removed the name of the chap who sent it as he never said whether I could name him. He is unknown to me anyway other than this email.
It refers to a couple of images. I am going to upload them to a yahoo album for viewing if possible as they are above limits of this site.

Hello Gordon,
As an enthusiast and businessman involved in image quality issues, scaling,
enhancement etc. I thought I'd take the liberty to write this message with
attached images I feel should interest you.
I have been reading a few threads posted on the the AV and AVS forums where
people are under the misunderstanding that it is impossible to generated
higher res real detail in an image than exists in the cptured source frame.
This in not entirely true, in that under curtain circumstances a
considerable amount of extra real detail can be extrapolated from a sequence
of frames and there are algorithms being developed that can genuinely
reconstruct the detail and edges in still frames.
These techniques are beginning to become more commonly used in post
production systems to some extent and real time consumer level systems
aren't too far away either I believe.
I have emailed to you a source (under-sampled/aliased) image and processed
image example to illustrate what is being achieved. These are genuine
images from prototype research systems. I don't know how to post these
images to the forum so if you wish to do so then please do, as I am sure
there will be some other members interested to know there is more to image
scaling and enhancement than they may have realised.
Many thanks.
