PVR Client question

Have a look at the addon "super favourites". Maybe this can help you achieve what you want.

Never worked for me...I tried this but no success..

If you're familiar with Kodi keymaps then one thing you can do is map the action "SendClick(28)" in the TVGuide section of your keymap to a remote button of your choosing.

This would mean you need to firstly go into the TV Guide, but from there you can then get to the Channel Groups dialog with a single button press rather than going to the left slide-bar then keying down and selecting the Channel Groups option.

For example, on my machine I have mapped "SendClick(28)" to my remote control's yellow button and it works a treat.

<TVGuide>
  <remote>
    <!-- Yellow Button -->
    <yellow>SendClick(28)</yellow>
  </remote>
</TVGuide>

I also have a "Guide" button on my remote which is mapped straight to the TV Guide, so I can get to the channel groups by simply pressing "Guide" followed by "Yellow".

If you haven't used keymaps before then this page should help:

28 is the ID for a built-in control within the PVR Guide which will take you straight to the channel categories selector. These hidden built-in button ID's aren't so easy to find, but are listed towards the end of the skinning manual:

Please note that I haven't tried this in anything other than the default Estuary skin so can't promise it will work in Aeon Nox.
