They probably have different revisions of the firmware. One of the directv
menu screens should show you the firmware version. You may
be able to force an upgrade (I have never tried, my D10's upgrade
when they feel like it). If it stays working you may not want to
though whichever has the older firmware will probably upgrade itself
at some time unless they are really different hardware versions of the box.

Its possible that changing the OSD off delay helped if the tuning was failing 
with the Excessive channel change retries errors. If it hadn't finished
the channel change when it got the next command it could confuse it.
To be sure you could temporarily change the script back and see if it 
stops changing with live tv.
