Some time back, I wrote about how I was struggling to mark tracks as podcasts in iTunes (unless iTunes had downloaded them itself from a feed). I never really got to the bottom of that but whilst I was on holiday recently, I missed a couple of episodes of the BBC 4 comedy show “The News Quiz” and the BBC’s Friday Night Comedy feed only contained the most recent episode.
A friend helped me out with the missing file (he had downloaded it as normal using iTunes) but, when I added it to iTunes, I noticed it was placed in the correct place in the feed. So, it seems that there is some metadata somwhere to mark the details in iTunes, but how I access that for older (pre-iTunes podcast support) episodes I’m still not sure…
