Interesting, I thought I had read every thing in the sdk. I had come across the the epgscene and grid posted https://forums.roku.com/viewtopic.php?f=34&t=88621&p=508624&hilit=epggrid.xml&sid=ec821f7b7ad75d065a7b5985e776faf2#p508624. After reading more post I came across a post from roku moderator that roku had pulled the documentation due to copyright situation. Not sure if this is the same one yet. I had the feeling as you stated that if the documentation goes away, the component will probably be taken out eventually. Thanks for the link. Thought maybe if you could see the component being extended might give idea on how to create one from scratch.
