Glad my post was of help. The status message pop up while more prevalent on the EZ Panasonics also happen occasionally with the ES series too. Most notably I was watching a show live through a ES tuner a while back and the MTS stereo signal kept coming and going for some reason(not the fault of the Panny but the broadcast). Every time it would change the OSD would pop up for a few seconds. After a few minutes of this annoying behavior I disabled the OSD messages and all was well. I normally do like to keep it on though, for one thing it tells you when you've paused or unpaused a live recording but when it becomes annoying it's relatively easy to disable.
I discovered one of the reasons for the status display popping up while watching the tuner. The status display will pop up whenever the program title changes in the PSIP stream, i.e., at the start of each program. At least you can categorize this as a "feature", albeit an annoying one.
