E2 is a total pain in the arse to get your head around first time for a newbie even if you are experienced with the older E1 based receivers. That said these days much in E2 has been automated or dummed rite down for the end use by the image teams.

You just need to persevere and ask question when you need help. For me E2 is far and away the best system at this moment for STB enthusiasts once you get around the initial steep learning curve.
