Use the directional keys on the wiimote for navigation.
Move the page up arrow from the top left to the top center, Move the Page down arrow to the center bottom. Its to easy to miss the small icon and click and play a movie.
In the More info, Make the close button (x) much bigger. Make the font a lot bigger.
Indexing :) I dont mind using a few cpu cycles to index all the subscriptions I have setup. This would be best during playon ilde time.
Auto Patching option.
Mark netflix, hulu, etc as down on the channel selection page when things are broke. This would of saved me a lot of time knowing that it was broke to begin with, then wasting time trolling forums trying to figure out the issue.
Clock, my soon to be old DVR has a clock, it would be nice to have one in playon.
Show the movie title in the control bar while its playing.

Thanks for the ideas! Some of these we're already working on for the next revision of the interface. But it's nice to get new ideas on the table.

Was also thinking if indexing the channels is not possible or to hard, it would be nice to be able to add objects to playons own queue or favorites if you will. Then just make that queue just another channel. Seems pretty easy to me in my head anyway.
This is a great idea. It's a bit tricky to implement, since PlayOn is dynamically generating the folder structure based on Internet browsing. And since the pages and feeds we point to change all the time, caching of specific videos and metadata gets tricky and can be prone to errors.
