Okay I Googled some more, and realised there's actually a couple of ID3 extended tags to use. I downloaded the software Mp3Tag, and noticed there are different extended tags (View > Extended Tags, or ALT+T) between a podcast that is listed in the list with the feed, and one that I added manually, namely:
- PODCASTDESC - the description of the episode, e.g. "Carl and Richard talk to Gus Issa..."
- PODCASTID - the URL to the episode, e.g. http://www.dotnetrocks.com/default.aspx?ShowNum=625
- PODCASTURL - the URL to the entire podcast series, e.g. http://feeds.feedburner.com/dotnetrocks_AAC
Also, I already had the below:
- PODCAST - the file is a media type of Podcast, i.e. value = 1
Now to find a way to automate the updating of this, have a lot of MP3s!
Update: To bulk update the fields in Mp3tag, you can go to Tools > Options, or CTRL+O, to open the Options dialog. In this, go to Tag Panel in the left pane. Add The above fields (e.g. PODCASTURL) in the Tag Panel list, and click OK. You can then select multiple items in the program, change their values, and press Save to apply the changes. Awesome! Then, delete the podcasts from iTunes, but choose the Keep Files option when asked what to do with the actual files. Then, drag and drop the files to iTunes to re-link it and you should see everything associated with the right podcast :)
Hope this helped someone, cheers,
James
