Generally poor audio quality on pod casts?

So, I note that Adam Curry’s pod cast seems to have vastly superior audio quality than the G’Day world pod casts I’ve listened to today. It actually makes the G’Day world stuff really hard to listen to, which is a shame as they have a fair bit of good content. I wonder if there is documentation online for what sort of configuration options people are using for their MP3 encoders?
