The new EPG is nothing to do with you upgrading your package - it has been a phased roll out for all the Samsung boxes, and it IS completely random!! Our Sammy box knocked itself off at about 11.15 on friday morning, 5 minutes later it re-booted and the new EPG was there.
Don't know quite why people were getting so excited. It's certainly in Widescreen, but it is not Hi Def as the cheesy advert stated. It's more Better definition than the old EPG! Looks better, but there is far too much going on - it would have been better to have the navi bar down the left hand side of the screen, and have items branch off, (like the review searches on this very site for example), this would really save clutter. then simply have the tv guide on when you hit a certain button. The mini tv is a rather indulgent addition i feel, that could be easily done without - exactly how long do they expect us to be looking for something to watch lol!
And as for adding ITV HD, there is so little on there it's criminal. And what's the point of having Star Wars in HD if you can't show it in the right format, full frame 16;9 and it had a distinct whiff of 'upscaling' about it. Hmmmmmm. I'l wait and see before i rubbish it anymore :-)
It certainly runs very quickly on our box, not the dog it seems to have been on other brands, but hopefully future software fixes and enhancements will turn it into the guide it really should, (and deserves) to be :-)
