Roku TV Guide Settings and additional functions

Hello Roku Community,

I am happy to be a member now and wanted to start with a question for you.

I bought a Metz Roku TV 55 inch and use some Roku sticks in my family. I found it charming to have a Smart TV with the Roku system and use the streaming apps regularly and without any problems. The performance is also fine. The sound also arrives perfectly via a Sonos soundbar using ARC. Now to my question. I still use linear live TV from time to time. The guide gives you a good overview of the current programs. Is it possible to add the following functions here? These are already standard on many Samsung TVs, for example. I am interested in the following:

• Starting and programming a recording via the TV Guide.
• Scheduling a time to switch to another channel via the guide.
• Complete display of information about the current program, as only a small part is currently displayed.

I hope I've come to the right place with my questions. Otherwise, I would be happy to receive information on where my query would be better placed or constructive information on my topics.

Have a good start of the week.
Kind regards,

Ronald
