The critical issue is to stop and restart the Media Center Server after any changes.
MrC, many thanks for the proposal above for grouping items. I have now done this for Albums, Artists and Movies. A bit of trial and error was required to get the right field names but they all work fine now. I was about to embark on designing some html and javascript to do something like this. Your solution was soooo much easier!
As a matter of interest, for Album grouping, I chose FormatRange([Album], 3, 0) as the expression and used your FormatRange([Album Artist (auto)], 3, 0) expression for Artists.
For Movies, I used FormatRange([Name], 3, 0).
One query I have - In the "All" grouping, the caption shows ( 8 ). This is obviously the number of alphabetic groups. Can this number be removed?
A second query - I have now done the same for Recorded TV. I have used [Name] - [Date Recorded] for the caption. The problem is that the date includes the time, which I don't want. Can I shorten [Date Recorded] so it just shows the date?
Many thanks,
Nick.
