This custom panel contains all fields which may be required for iTunes podcasts.
If your podcasts are MPEG-4 files (m4a, mp4, etc.) you should enable the Preferences-File List-Do not enforce formatting of the Year field option. iTunes will only read the release time for these files from the Year field. In MP3 files, they will read the Release Time field.
The content of the Podcast URL field is irrelevant. However, the field must not be empty for podcasts in MP3 files. It is a good idea to always put something in the field.
This content must be imported in the Custom Panel Editor.
