The whole point is that MythTV really needs to know what channel your 
cable box is showing, it can't do that if it can't control the box.

MythTV works very well... It just _has_ to be set up first!

Erm, not with anything like what MythTV gives you, the windows software 
is a basic VCR, if you want that MythTV is not for you.

The basic UK set-up gives you just about everything you need. You have 
to tell it which channels you're subscribed to but that takes all of 
about half an hour (you'll need to know the xmltvid names that 
radiotimes uses for each channel [tv_grab_uk_rt --list-channels] gives 
you them - they look like URLs.)

MythTV isn't a VCR, it's a PVR - it relies on knowing what is on and when.

You might be able to reduce the delay if you alter the source and 
re-compile, otherwise get used to it. Once you have everything working 
you'll not be watching live tv much ;-) The minor delay (due to 
buffering) is worth it to be able to pause & rewind.

If you've not set it up properly it won't know which (radiotimes) 
channel maps to which (in Myth).

Yes because when you tell it to record it uses the tv-guide to know when 
the program ends.

Once you've got it set up you'll never go back ;-) A few hours fiddling 
around is really worth it!
