There is a beta update available for buzz 5
Home page check for updates
When it says no update available Type 2015 on remote If it says no beta available your mac will go on a list for next week
I would wait till then to troubleshoot issues
the box appears for me when the recording is about to start
I reported it
if the epg is broken down into two half hour episodes you have to do two recordings
thats how it should be if recording from epg
