There is a way it can be done and it's really easy.
Just use your Telus remote, and press the "Options" button, which is right below number 9.
You will see a menu appear on the right side of your TV screen.
Scroll down until you have highlighted "Favorites List", and press the "OK" button in the middle of your remote.
On the next screen you will see an option called "Subscribed Channels", highlight this option and press the "OK" button.
Now you are done, when you open up your guide you will only see the channels that you subscribe for.
There are certain exceptions, such as Pay-Per-View and Video On Demand Channels.
Note: You will have to do this for each of your Telus Optik Tv boxes that you have.
Hope this helps
