I've lost count of the number of times I've sat through a recording of a TV show, adverts and all and then had either one of two thoughts
a) Hang on I didn't need to watch those adverts.
b) Actually those adverts were more entertaining than the program.
The point is that a lot of the profit made by commercial TV is from the adverts so as far as I am concerned I am doing them a favour by recording them.
I 2nd the motion to get a refund on watching 1.5 hours of dross. I particularly hate the Discovery channel stuff that crams 10 minutes of program into 1 hour.
