Hi @BuckshotTom58,
Welcome to the Roku Community!
We understand that you would like to use your Sony TV remote to control the Roku Live TV Channel Guide when selecting a channel. We are happy to assist you with this.
Please note that Roku does not have a feature that allows you to search for or jump directly to the channel you want to watch on the Roku Live TV Channel Guide. You will need to scroll through the channels manually. As a result, the Sony TV remote will not be able to perform this function either.
But no worries, we will let our Roku team know about your input. Thank you for your understanding.
Cheers,
The Roku Community Team
Riamie D.
