ITunes' podcasts no longer download (?)

Question

iTunes' podcast downloads had for the most part been downloading fine until the partition that they had been on was deleted and I had to recreate the iTunes folder on that partition from a backup.
When booting from my primary drive using 10.3.9 I can no longer manually, or automatically, download podcasts. And oddly, even podcasts that exist on that partition will not even open in iTunes.
Yet... when I boot from 10.4.9 on a secondary drive which shares the same recreated partition with my iTunes folder (with the podcasts on it) I can download podcasts manually and automatically and it will play all of them without problems.
Common sense would simply be to delete the com.apple.iTunes.plist and maybe even the com.apple.iTunesHelper.plist files. (Which I did.) But this didn't work even though I did this with iTunes inactive and rebooted. So... it would seem that the next step would be to reinstall iTunes. So I deleted both the iTunes app and the preference files again and rebooted. Still my podcasts won't either manually download or automatically download and the really strange thing is that the ones that were downloaded while booted from 10.4.9 will not play when booted from 10.3.9.
I then resubscribed to the broadcasts (i.e. podcasts) and though the available podcast lists appear for each broadcast with "Get" next to each... when I click on them they won't download and I get the icon at the far left showing there is a problem.
Though this might be a prebind problem for the last issue... I don't see how that would affect iTunes not being capable of downloading podcasts from 10.3.9.
Any help would be greatly appreciated.
I've been listening to iTunes' podcasts for years without this problem so I can only imagine that it must have something to do with the fact that the partition had to be recreated (though I can't see how that fact would affect iTunes in this way when I DIRECTLY drop the podcast files on to the iTunes app icon... and they still will not play. This would bypass any prebind problem it would seem).
Thanks for reading this lengthy post.
Systems 10.3.9 and 10.4.9 on separate internal drives in the same box using iTunes 7.01 (7). Though I had been using iTunes 6.05 with 10.3.9 before this problem occurred. But when I couldn't solve the problem I upgraded to 7.01 with 10.3.9 -- since it was working with 10.4.9 I thought I'd give it a try -- but even that didn't solve the problem.)

Answer 1

It appears that I solved the problem. (I like to post my solutions so as to both not waste peoples time and so that if this ever happens to someone else it might help.)
My iTunes alias of the iTunes folder that is by default placed in the Music folder (i.e. ~/Music/iTunes) was broken after the partition where I had moved it was recreated.
Or... since I also forced a re-prebinding (not a simple 'update prebinding') it may have been this since my music in the same folder (on the recreated iTunes folder on the recreated partition) was playing fine and from 10.4.9 the podcasts played fine.
So it may have been both... but anyway... the podcasts are working fine again.
