Song NEARLY imports, then have to force quit.

Question

Hello all,
had some great advice here before with success, but this time I fear it may be a dead end. A little background info then in point form may be in order this time:
1. Have recently upgraded to iTunes 7.1 and 7.1.1
2. Successfully imported 1000 songs so far with bought and copied CD's
3. During latest incarnation of iTunes have also been able to import CD's with 'data protection' (in the same box set however some just get ejected after loading straight away).
4. COPIED VERSIONS I HAVE IMPORTED IN THE PREVIOUS VERSIONS OF I TUNES ARE NOW LOCKING ITUNES AND I HAVE TO FORCE QUIT EVERY TIME.
5. I have highlighted the above as with the remaining 10 CD's (purchased and previously burned) this seems to happen.
6. Have tried importing using various formats: AAC, MPE3, etc without success.
7. Superdrive was recently replaced.
Now, where it all goes South is the last few millimeters on the import bar in iTunes, on the first song, before the lock up.
Data protection I can understand but please bear in mind that those CD's have been imported OK in the past but now won't.
Also, some of those Data marked CD's (I had previously imported) will simply be ejected if iTunes is NOT open, others if iTunes was previously closed.
Seems to be little pattern in it at this stage except of the 'upgrade itself'. If the CD's (burned or bought) load, the force quit always seems to have to be initiated during the last few seconds of the first import. Tried also to uncheck the 1st song, with the same result.
If anyone has some pointers, let me know and we can try to narrow it down. My whole reson for importing is that ALL our 10 year collection was the victim of a break-in and I would like to secure this through back-ups nowdays.
Cheers
PS Excuse the untimely replies as Australia is many time zones away.

Answer 1

Well, after my posts and updates I have finllally imported nearly 1800 songs. The main work around for those that locked up iTunes just before the 1st import has always successfully been: Play first song and then import (something certainly new). The remaining 3 CD's are even a stranger even:
1. 2 burned CD's are shown as 'empty' (zero data) and won't mount. Have previously imported some songs from those CD's and there is no problem playing them in the home CD player.
2. 1 bought CD 'cycles' through reading and then ejects itself. Whilst it has 'data' on the reverse of it, I have imported one with an identical print (even came from the same box set).
Could this change maybe have to do with region code more than iTunes and OSX update? I did mention that this is a new Superdrive as well. When I get the chance, will try them at an Apple store and see what happens. How annoying though, only three to go and all my imports are done.
Any tackers on this final problem?
Cheers
