I found a problem (it was in the previous version too) when you cancel a recording the show stays red. I have to go back to the menu and return to the guide for it to be updated (shows green).
I just tried it here and it worked ok for me. I know it happens asynchronously though, and if it takes more than a second or so, then it'll continue to show it as read, so I'm guessing its just taking a little more than that on your machine. Reproduce the problem, then zip and attach the logs and I'll see if anything stands out..
