I tried the new interface today after the notice of the update related to Flash support going away. I like that you can now see the amount of free space on your PVR.
Unfortunately when viewing recordings or scheduled recordings there doesn't appear to be scroll bars or any way to navigate the lists. I've tried both the latest versions of Firefox and Chrome and can't seem to scroll through the lists.
I'm pretty sure they're aware, but I'll bring it up with the team to be certain. I support Pik, which doesn't have PVR capabilities, so I don't have visibility there, but can pass this to the correct person.
