Thanks. None of my three have been upgraded yet but not sure I am really wanting it. They have been rock solid. (with a little help of a cooling fan and making sure they get rebooted each day)
Got my update and noticed a few things moved around (including CC), but otherwise seems stable. Hopefully this will make the freezes disappear, or at least reduce in frequency. (I've been hard-rebooting it because it locks-up/freezes probably 3 or 4 times a week lately).
I got the update last week and the first thing I noticed was the HD channels and HD recorded content is twice as loud as SD channels and recordings. Also I do like how it hides the SD channel when the HD channel is available.
The other three 612 receivers still did not get the update yet. Mine is a older one from 2008 as the other three are from 2011 which is why I probably got the update first.
