True but you cannot copy/paste from the infomation dialog (at least with iTunes 6.0.4.3. Ive found that the best way to do this is;
1) Export library to XML
2) On friends machine import XML
3) I tunes will import the Podcast URLs but not the individual episodes, it will complain that it cannot find the file
4) In turn click on each podcast - press unsubscribe then press subscribe then download each Episode.
Works for me and only took a few minutes (except for the time it took to download the episodes)
Thanks for your help
