I just realized today that this issue has resolved itself for me.  I made no changes and was just occasionally checking back for any news on a fix, then I kind of forgot about it until today.  I was getting the "Press OK To Browse A List Of Recordings" banner at least once (usually more) during the playback of every recording using a wireless receiver.  I also noticed that after the first time restarting a recording  the volume of the playback would get annoyingly low and I would have to crank up the volume for the remainder of the recording.  Hopefully this was fixed for everyone, but unfortunately I don't have any more information.  Maybe AT&T finally did release a fix?
