What you have to do is delete the video podcasts, then leave iTunes sitting there for a couple of minutes. It tries repeatedly to save the library and throws errors, but once you 'fix' it by deleting the podcasts you have to leave it long enough to try and write the library so that it can succeed before you shut it down. Once you leave it for a few minutes without errors, you should be able to close it and reopen as normal.

But I have no video podcasts. Obviously, something else is going on here.
 
Fixed!

The workaround posted by villaCr did the trick.....

1. Open iTunes, and go to File->Export Library
2. Save the library somewhere in your hardrive
3. Complete and close your iTunes
4. Go to your music folder, open the iTunes folder and move to another location both files: Itunes Library data file and the iTunes Music Library.xml. DO NOT REMOVE THE FOLDERS.
5. Open iTunes again, and it should show up that your library is empty.
6. Go to File->Import and load the previously exported file.

The Library import will take a while, but after it finishes you will have a new iTunes library with all your stuff in it.


No more errors and I didn't have to revert to an older version of itunes. Thanks villaCr!

Doesn't this reset your play count, import date, last played, etc.?

It does. And as a side effect marks all podcasts as not played, and made my iPod believe this was no longer the computer it syncs with. iTunes would then have to empty the iPod and re-sync from scratch.

A different fix! (if you have customized Sort fields)

For me the problem was not video podcasts; it was that I had customized some of the new "Sort" fields introduced in the last version.

I could tell it was a problem because I had used the sort field to sort by last name (for example "Simon, Paul" instead of "Paul Simon") and it was sorting by "Paul Simon" even though the sort field said "Simon, Paul". But after opening the information panel and hitting OK, it did sort it by "Simon, Paul". So then I had two Paul Simon entries, one for P and one for S.

I then fixed all my entries by viewing all the songs, going to information for the first, and clicking Next all the way through. Boring but it worked! I also only had about 800 songs, so it wasn't actually too bad.

And after that it was able to write the library!

I also want to comment that the new version does the "right thing" more often when you're using the new Album Artist tag; if the Album Artist is the same for all tracks in an album even though one of the tracks might be different, in the Artist listing only the album artist shows up. For example, I have a BBKing album with a track by "BBKing and U2"; it formerly had both listed under Artist, separately. Now only BBKing is listed, because BBKing is the album artist for all tracks! However, I do have one album that it guessed the artist name wrong, so to use the above example, it was calling "BBKing and U2" the artist for all tracks on the album instead of just "BBKing". But generally I'm more pleased with the sorting in 7.3 than in 7.2.
 
Deleting the video podcasts worked for me- thanks for the advice here. Hard to believe that this hasn't been addressed by apple yet though...
