Play a HD source - either a 720p channel from sky or telewest or free using astra sat gear, and you will notice the difference as your "100Hz" set cant process High Def resolutions - so no your CRT tv wont benifit a HD signal.
However, you can get HD CRT telly's - few and fair between and they only support 720p (i believe).
Wouldn't say I agree with this 100%. If your CRT TV can downscale HD signal then it will give a better picture as even downscaled you will be left with a PQ than normal SD can provide.
Even ignoring the downscaling side of things you could get a better picture out of the HD box onto a SD TV even through scart - yes you are only getting a SD picture but the box internally will be downscaling the HD signal to SD and as before that will leave you with more information than a normal SD broadcast signal has.

Yes it will play - as I have said before but playing does not mean you are getting HD IMO. The minimum resolution for the lowest HD is 1280x720 thus 1024x768 cannot show this in native or upscaled as you do not have enough horizontal pixels

It can't leave you with more information over scart.
Downscaling is throwing that information away.
As said in my other post though, if the material has been recorded in HD you will be getting full use of all SD can offer and it will look quite good as people are seing with the football.

£800 as its some Denon one.
We will do, but having just paid the £200 for Sky+ just after Xmas its seems pointless to pay another £300 just for the WC. We may aswell wait for it to drop right down afterwards when more and more UK stuff is in HD aswell.

It can leave you with more information - even with scart.
If you feed a TV a normal SD TV signal and feed it a downscaled HD signal there would be more information in the downscaled signal as it would be less compressed.

Rob, your right mate - 180i/720p requires a minimum res of 1280 x 720, though from what i remember, the downscale to 1024 x 768 is minimal in picture quality.
As with a HD signal improving picture quality on a CRT - isnt the HD signal only outputted on the HDMI/DVI sockets on the skyHD/Telewest/Astra boxes (if memory serves me right)? therefore your going to need a descaler (which throws picture information away as john said) leaving you a picture that would be pretty similar to an standard 480i feed from a digital source (sky/telewest/ntl/freeview)?
Technically i can see that the picture quality should be better, but unless you have the money for a decent descaler (Runco, Miranda etc) then i doubt picture quality would be noticable.
