Problem is resolved.

Logically the problem seemed to be with file permissions.  Files are on an 
external drive so all user accounts should normally have R/W access by default 
(I think).    Don't know why this set of files needed special treatment.   From 
User1 (admin) and using Finder Get-Info for the folder containing all problem 
movies I gave full R/W access to User2 (again).  However, this time I had 
deleted all the un-editable movies from iTunes for User2.   And this time it 
worked.  The subsequent reloading of the movies into iTunes gave User2 full 
rights to edit metadata and change the Media Type to TV.

I did not turn File Sharing on to make the change to User2 privileges as this 
is just one computer, not a network.  All help on file permissions I could find 
were based on the premise that File Sharing was a necessary first step.    But 
NO help forum covered the situation of accessing  files on an external hard 
drive.

Well, we try things and learn from the experience.

Cheers

Hi Wamuggers

I have two User Accounts on my iMac and the problem is associated with User2.   
iTunes metadata for just one set of movies (40 files converted from VHS tapes) 
can not be edited, while the Options/Media Kind choice is greyed out.   I want 
to mark these movies as TV Episodes.   Other similar ex-VHS movies give no 
problems with fully editable metadata in User2.    Metadata for the "problem" 
movies can be fully edited in User1 account, hence the finger of blame is 
pointing to User2.    Any suggestions to fix the editing issue in the User2 
environment?

Most of my movies are stored on an external hard drive with only their links 
copied to iTunes.   Normally the movie links copy across as 'Films'  but  I can 
change the category in iTunes metadata (through Get Info) to 'TV Episodes' etc. 
 Movies for User1 and User2 are kept separate - no dual entries in their 
individual iTune libraries.    User2 is a new clean account with standard 
preferences.     

I did a full shut down of the Mac to clear away any loose bits and bytes but it 
had no effect on the problem.    I am using an iMac with OS 10.6.8 and iTunes 
10.3.1.

A strange result from User2 Finder may be relevant.  The file Get Info "sharing 
and permissions" information show a few variants, most with "you can only read" 
and some with "custom access" with the privileges table greyed out.   I used 
Admin access to modify one file for full read and write access and read and 
write privilege.  However this had no effect on iTunes metadata access - still 
greyed out Media Kind choice and the other tabs/fields not editable.    I don't 
think that "sharing" should be involved on just the one iMac anyway.   But all 
the "good" movies in User2 have nice clean read/write permissions and 
privileges.

Another Clue (or red herring): These particular movies were originally set to 
Media Kind = Podcast in User1 iTunes library.   It seems that some, but not 
all, metadata editing done through iTunes is written back to the original files 
on the external drive.  (For example, files remember the Description field data 
but re-set the Media Kind back to Film.)  Perhaps there is some some residual 
podcast metadata impacting on User2 editing.

And Clue 3:  Just one of the problem movies had been written to a backup drive. 
   When the file was directly option-copied from the backup drive to User2 
iTunes, metadata could be edited and the file successfully marked as a TV 
episode.    However when the file was firstly copied to the normal movie hard 
drive (but to the root directory) and then option-copied to User2 iTunes, 
metadata could no longer be edited.   At the time of the backup this first 
movie would not have been set as a podcast.

Alan
