Removing unwanted or pay-per-view TV channels

Many of us have access to 100s of TV channels and of course our TV is not smart enough to not show us the channels we don't pay for. Every time you change channels and go over one of them, you're TV will freeze some 30 seconds, then display that you need to buy this channel in order to view it.

Which is true, but how frustrating. I'd rather have my TV only show me the channels I can see, and if it could also skip these advertising channels that would be a bliss.

This is actually possible and even simple, activate the parental control on your TV and set all these channels as 'restricted/adult only', now enjoy surfing through your TV channels.
