Press page up/down/blue.That will take you into the on screen panel(not the engineers only panel tho) Go to page 3 & look at 'conn status'It should say '5 conn' (or connected)
Anything else & the VOD/Interactive wont work .
As for the software update,I dont think so as it's going to be changing more frequently than Sky as we put more stuff on.And splitting the feed for a CM is commen practice & in the SOP.As long as he checked the levels thing should be ok.TIP' If you are having problems with the CM,do the up/down blue & look for 5 conn.That will tell you if the return path is working.Anything else than 5 conn,no return path!Get a tech out!!
