As a whole, it seems slower. The mini guide jitters when going between channels whereas before it would be an instant transition. The guide, even though has a better layout, is poor. I just expect to get the 'Program Information Unavailable' or whatever it says every time even though it loads up after 20-30 seconds per page. At least it actually eventually works now.
Though my biggest gripe is the removal of the +/- 100 channel skip. That was invaluable with the big blocks of shopping and kids channels
But....that two way tv is great, must of run up the bill with those annoyingly addictive games
Still tbh, i'd prefer to see etv up and running properly before (hopefully) other changes.
