Hi, will do on the upgrade. In the meantime, I've fixed my issue, and found a bug in the process:
For the Pink Floyd Blu-ray item, I set 'grouping' tag to "Audio" and updated the file view filter for Audio with a custom one (that was the trick); this filter will now display all items with value for tag "Media Type" == audio or value for tag "grouping" == Audio.
Procedure:
1. <right-click>Audio -> cusomize view -> settings -> set rules for file display
2. delete all rules
3. create custom filter:
a. (left pulldown): Custom
b. (right field): [Media Type]="Audio" or [grouping]="Audio"
4. click <ok>
5. click "overwrite"
The bug is in that when the "set rules for file display" form is shown again, it doesn't show the rule as "custom" but instead interprets what was entered as multiple rules; if I click okay, the results will not be equivalent to what the custom filter provided. Ex.
Media Type contains Audio
grouping contains Audio
I think this is flawed because each line appears to be AND'd together, not OR'd like what I needed. I think if you enter a custom rule, it should display it as originally typed or at least displayed in a way that has equivalent logic, if that magical step of splitting the logic up is even necessary. It also seems odd that it would fall back on a pattern match ("contains"?) vs. sticking to string equivalence (==, is, eq, etc); I would think that would slow slow the process down considerably. Sorry, I do software all day.
Thanks for the help!
