Season based info is along the lines of.........
Season 01 - "Prince Edmund, a.k.a. the Black Adder, constantly schemes to take the crown from his father and brother with the help of Lord Percy and Baldrick."
Season 02 - "Lord Edmund Blackadder is now seeking the approval of Queen Elizabeth I with the "help" of Lord Percy Percy and Baldrick."
I guess most series' which have seasons would not require such info as it's generally more of the same and the info at Series level applied. With the BlackAdder seasons (I assume it must apply to others also!) they are set in different era's so a different description is applicable.
It works well when I have the folders named 'Series' but I think that is because MB only seems to allow 1 level of Series descriptions. It did work nicely also in that the Season description in the season sub-folder was getting picked up in MB and displaying instead of folder name - so 'Series 01' was changed to '1 - BlackAdder I' . But, like I say, as soon as I change the folder name to 'Season 01' this stop working. I think due to the fact that MB then uses series.xml at the root folder to display series info, it then won't use the sub-folder series.xml.
This is fair enough if this is how it is intended to work (and TVDB doesn't have the concept of Season specific info). I assume I can rename my folders 'Season 01 - BlackAdder I' and MB will still recognise it and use series.xml file for series info? This might be a bit anal but the later seasons do change their titling slightly (eg. 'BlackAdder The Third, BlackAdder Goes Forth') so I thought it 'important' to display the real season titles (as oppose to just 01, 02, etc.).
