In the last week or so, I have encountered problems with iDVD., When I try to create a Slideshow, by dragging photos into the Slideshow pane. the dotted outline of the slide appears, with its title and comment, but the thumbnail never eventuates. The spinning lever keeps spinning until I quit.

I have:
• rebuilt my iPhoto library
• trashed the iDVD plist
• used terminal and typed " Code:chflags -R nouchq "UNIX\Path\to\my\iPhoto\Library" ( this was suggeste by a poster on Apple's own forum).
• re-installed iDVD 6.0.3.
all to no avail.

Any suggestions of what I could try next ?

TIA

Mac OSX 10.4.9, iMac G5, iDVD v 6.0.3
