Dave/UK History has confused an awful lot of boxes, because UK History is still there, but is on a different mux, using the space that belonged to UK TV Bright Ideas, while Dave is now using the space that did belong to History, but the LCN from Bright Ideas.

So, from one perspective Dave is UK History, just with the name changed and a different LCN; name changes are picked up automatically, but not number changes, hence much confusion and UK TV telling people to do a re-scan.

Easiest thing to do is to delete Dave, and UK History, and Bright Ideas if you have that, and then scan. Or just delete all and rescan.

The toppy keeps the program details of each program which is much better than any preview clip.
I've got episodes of the professionals saved on both machines and its much easier to find what one to watch on the toppy. Most of the time on the pioneer with the preview that doesn't keep the program details just the name, date, channel etc if its even got as far as showing the actual program and not the ads then it's usually just into opening titles thats in the preview so got no idea what episode it is. Take a look on the topfield though and it tells you the program details and immediately you know which episode it is.
