I took a look at IMDB and found the following,
(there have been some glitches in processing episodes, usually punctuation and the use of '&' or 'and')
The Simpsons broadcast ratio format
(it's being taken that up to the start of series twenty, all episodes were broadcast the same at S20, Ep1, there were changes to how the sound was broadcast, but this is for aspect ratio)
Series 20 Ep 1 - Runtime: 21 min, Sound Mix: Dolby, Color: Color, Aspect Ratio: 1.33 : 1
Series 20 Ep 21 - Runtime: 21 min, Sound Mix: Dolby, Color: Color, Aspect Ratio: 1.78 : 1
Series 22 Ep 1 - Sound Mix: Dolby, Color: Color, Aspect Ratio: 1.78 : 1
Series 22 Ep 21 - Sound Mix: Dolby, Color: Color, Aspect Ratio: 1.78 : 1
Series 25 Ep 1 - Sound Mix: Dolby, Color: Color, Aspect Ratio: 16:9 HD
Series 25 Ep 21 - Sound Mix: Dolby, Color: Color, Aspect Ratio: 16:9 HD
This shows when the aspect ratio changed for the original broadcast dates
Spoiler: show the 685 line series.info file
Did a bit of editing on the series.info file (by the way, where can they be found)
There are two resulting files, the first ending in S00, puts each episode based on the episode's title being in the synopsis in its applicable series sub-folder, so a twenty-one episode series would/should have twenty-one episodes
The second file, ending in S00, Ep00, puts each episode based on the episode's title being in the synopsis in its applicable series sub-folder, so a twenty-one episode series would/should have twenty-one folder each with one episode
If it turns out that each episode folder has more than one episode, it means you have more than one copy, recorded at different times
There are certain requisites that need to be met, this rule needs to be placed in a folder named [ The Simpsons ], the system needs to be set to do auto decrypt and auto shrink
If this rule is the only rule on the Humax HDR Fox T2, there must also be a rule at [ /media/My Video ]
The Custom Firmware and Sweeper need to be installed, not sure what else would be needed
To use the files, only one file can be active at one time, open the file in a text editor, copy and paste the file in the [ Text Editor ] window of the [ Sweeper Rules ] window
lcn 4 = Channel 4
!flag ODEncrypted = Not Encrypted
flag Shrunk = File is Shrunk
synopsis {Simpsons Roasting on an Open Fire} = Synopsis has the episode name
/media/My Video/The Simpsons/S01/Ep01}} = Folder where the results are placed
It may be necessary to split the file(s) into smaller blocks to process fewer series/seasons
If I have missed anything off, please let me know
