I'm using the Android beta but noticed that when scrolling deep ahead into the guide (12/25) and selecting a show to record, the guide does not change to make it evident it is recording. It does not turn the block "gold" nor does it seem to change any text or button option in the program entry to indicate it's now set to record.
Only going into the schedule and verifying it that way could I confirm that the show was set to record. This happened for multiple shows.
