Something that's been bugging me with the grid based EPG since moving from a Topfield a year ago is the slightly odd experience it gives regarding selection. It has a tendency to walk across the screen as you move up and down. Take this example:
For starters, opening the EPG places the selection not on the timeline but on the weather which doesn't start for another 10 minutes!

If I scroll left onto Graham Norton, to get back on the now timeline, the order of selection is as follows as we scroll down:
- Diagnosis
- Piers Morgan
- Ramsay's Kitchen
- Criminals, uh, not Superorgasm? That's a shame :-)
- Utopia
- Attack the block
- QI
- Worlds Most...
- Gogglebox
When what I was really interested in was what's on now.
Amusingly, this evening, as I scroll down page 2 it works its way left back to the current time again:

I am indeed fortunate today :-)
It seems that the logic chooses where to move next based on where its just been using something like the nearest midpoint intersection. This seems a sensible approach, but leads to scrolling up and down not always returning you to where you started from.
If you consider the purpose of the grid based EPGs, compared to the single or the multi, it's about seeing a simultaneous view of what's on now or at a specifc time across a range of channels. You indicate the time you're interested in by moving left and right, once you've picked that time, you move up and down the channels. So, if the EPG kept track of say, the start time or midpoint of the selected cell when you arrive on it using left or right, and used that time to work out what to select when moving up or down, then the selection would remain within a narrow time window. Benefits being
- Scrolling down the now timeline would remain on the now timeline
- Scrolling up would select the same events on the way back up
There are also a few performance issues with the grid EPG, which seem to be related to the number of cells being created. On my XTrend 8500, it takes in the region of 500ms to get something up on screen, or to scroll to another page of channels, but much quicker on the final page where there's only 2 channels to show. Moving around within a page is fine. The single channel EPG or the Movielist are more or less instant openers. I'm wondering if there's some optimisation that could be applied somewhere to make it a bit more snappy. Switching to the text EPG seems slightly quicker, but not significantly so.
