Thanks Sorceror and stormeh. I only have the analogue Guide Plus which is updated via Sky so I wonder if that effects the use of the 'Info' button as it doesn't seem to do anything when I'm watching TV channels. Maybe it only works with Freeview channels. I'll check again.
The display button does indeed provide lots of useful information (it's nice to see the bit rate) but the remaining time cannot be shown on the unit's LCD display, only on screen. I can live with it and am so far very impressed with the unit.
I also like the improvements to: 1) Speed and response of the unit to disc loading and menu commands, 2) DVD layer changes which are much quicker and barely noticeable on some discs. 3) RGB input via Line 1 4) Moving thumbnails for titles that have been recorded
