iMovie and iDVD - Updating

[Ian Tucker]

1. Despite having iMovie and iDVD Appns loaded onto my computer , 
Software Updater never shows available updates for these .  Is there 
any way I can get them included?

2. On checking the Apple web site today I noted there was an update for 
1DVD 3.0  to 3.0.1.  I downloaded this, but I cannot get it to update  
ie. I get as far as the "destination" disc window which shows red stop 
signs with exclamation marks  on both my main Hard Drive as well as the 
second HD and if I click onto the either of these HD's I get the 
message,  " You cannot install this Software on this Disk.  The iDVD 
Application was not found in the iDVD 3 Folder, within the Applications 
Folder of this Volume."

I have tried altering the names of the iDVD Appn. folder and the actual 
Appn within  from iDVD to iDVD 3, or iDVD 3.0, but with no joy.   I 
seem to have everything in the right places.

I am using a G4 with OS X 10.2.6 and the iDVD Appn was installed from 
the "iLife" DVD package.   Prior to using the iLife DVD and following a 
suggestion made on the List,  I hived off iMovie 2 into its own folder 
and this caused a couple of hic-cups with carrying out updates for 
iMovie 3, but I fixed that issue with retitling 1Movie 3 as required.   
As far as I can recall I have not previously interfered with the iDVD 
folder title, or the actual Application within.

Any suggestions please?
