Well had a letter through from sky that they were putting up the prices £10 a month :
Right, sorry for delay in replying. £10 a month, to me it sounds like you've signed up to something without realising it? Lets assume your bill is £50/m that is a 20% price increase, Sky are not that foolish.
You recently said you applied for an on-demand router, are you sure you've not added Moves,Sports ect? What exactly does this letter say?
when i tried to get the films they didnt come up so rang sky and they said oh you got to pay extra for that
If you get films on your standard TV setup, you will get moves through on-demand/xbox/mobile devices free. There are no extra charges for on-demand content, it should match your standard subscription. If you have been told different, its wrong.
Worth pointing out that Sky's call centres are often out-sourced, results can be varied.
Same here. I can't think of anything that was on any type of pay TV that I really felt that I absolutely had to see or would have paid to see.
If you cannot see any improved with HD, you are either getting 720p not full 1080p HD. Also you could have a shite TV which is not actually giving HD image. Finally you may just have shite eye-sight, if so, get an updated pair of glasses!
HD is
vastly better, you can easily see this on NewsHD channels as they can display significantly more detail. In comparison to me, SD looks very blury!
But surely people could just say that they only watch catch up TV to the tv licence people and still watch TV and not pay for TV licensing
.. Confusing 
TV License is there to watch a program
live, as it stands if you can prove (very hard to do so) that you only watch programs as VOD (after broadcast), you don't need a TV License.
