I have tidy installed and as far as I can see it just has to be 
selected/checked as an option too work (which it is). PHP? (Whooosh - as 
it goes flying straight over my head! :-) )

I was just double, double checking and also tried konqueror as well, and 
when the validator page is use in that, it's spitting out the same error 
as when I use Opera.

Google chucks out a couple of possibles, but I don't follow what the 
validator means by "prolog"? i.e. whether it's referring to the xml 
declaration or the DTD (or both?). As far as I can see, the

*<?xml* version="1.0" encoding="iso-8859-1" *?>*
*<!DOCTYPE *html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"*>*
*<html* xmlns="http://www.w3.org/1999/xhtml"*>

coding looks correct - the only thing is that the <!DOCTYPE and > ending parts of the DTD are being highlighted in brown (which I doubt shows up in my post)
and I'm wondering if thats giving me any clues? I can't think of what else too look at?
