I recently picked up one of the new reference design remotes (G10) now coming with many of the new Google TV stream boxes. I am using the remote with my CCwGTV as it includes channels up/down buttons. With Channel Button Detector setting enabled, the livetv button on the remote automatically opens Channels and the channel up/down pages up through the guide which are big improvements over the standard CCwGTV remote.
I have noticed an issue when using the channels up/down buttons when scrolling through the guide. The channels up/down button will work for a few pages, and then the scrolling stops. I discovered that the cursor/selector which normally highlights an individual TV show in the guide, disappears from the screen when scrolling fast and you can no longer select anything. At first I thought Channels app had frozen, but selecting back on the remote pops recovers the cursor/selector. It appears there is a bug when rapidly pressing the channels up/down button button.
The channels up/down button works fine in other apps, so it seems to be a bug with Channels. The only other suggestion would be to map the bookmark button to switch between the last and current channel which is available on the Tivo Stream remote.
If this bug is fixed this new reference design remote will be a game changer for us Google TV users.
Here is the new remote:
