Podcast /RSS feed issue

Hi

I use wordpress to publish my podcasts. I’ve set up a podcast category in order to generate a RSS feed just for the podcasts. I then send this through feed burner to iTunes.

The problem is that now I have more than 10 podcast entries on the blog, the old podcasts drop off the end of the blog ‘page’.

You can see the podcasts here: http://www.imakeguernsey.com/archives/category/podcast. But this is only the most recent 10 episodes. The first few are on an ‘older entries’ page here: http://www.imakeguernsey.com/archives/category/podcast/page/2/

This means the RSS feed doesn’t pick up the old episodes and as such, I only get the most recent 10 episodes in iTunes.

I just cannot figure out how I can get all of my podcasts to show up on the feed and then in iTunes. Lots of people manage it so it has to be possible.

Please help. Thanks!
