I just picked up a philips 43pus7334. I'm coming from a 43pus6401 which also ran android tv but i'm loving the jump up to this model so far, much faster and more responsive and makes me a lot more confident about android tv as its now not as sluggish as I thought it was. However, I have one issue which is doing my head in and I can't figure out.

My TV remote has a button called "TV". When I press this it goes to the Philips TV program and plays the google play trailers channel. I am using a HDHomerun to get my other TV channels and I can see them fine in the philips tv app. However, even if the last channel I was playing was a HDHomeRun channel and I go to the Android TV homescreen then press the TV button again, it will go back to the Google Play Movies trailer channel again. No matter what I do, whenever I press that TV button, it goes to the play moves trailer channel. How do I disable this channel from showing up at all?

Things I have tried so far:

Disabled the play movies application - This did not remove the channel. When I press the tv button, it still goes to that channel, the only difference is it won't actually play any video or audio, just a black screen.

Locked the channel in the philips tv guide - This didn't stop it from defaulting to it either, it still opens up and just asks me for a code now

Before anyone suggests live channels, I am already using it and have disabled it in there. I don't have this issue in live channels. However, pressing the tv button does not open live channels, it opens the philips tv app, so I want to get that working right so I can just press TV and it will go to my last hdhomerun channel rather than going to the play channel, and then I have to change the source to hdhomerun to get the channels I actually want.
