iTunes Empty After Restoring from Time Machine Backup

I'm wondering if anyone can help me out.

I recently upgraded from a 2009 MacBook to a 15" i5 MacBook Pro.

When I was setting up the MBP, I opted to restore from a Time Machine backup and expected everything to go off without a hitch.

When I opened iTunes though, everything was blank -- no songs or videos were listed at all. My playlists were still there though but also blank.

When I checked my Music folder in Finder, everything was still there so I tried manually adding one mp3 to see if it would show up on iTunes. iTunes just played the mp3 but it still wouldn't show up in the Music list.

One more problem I've run into -- Quicktime refuses to play my avi files, even with Perian installed. These are the same avi files that I used to be able to view on Quicktime on my old MacBook, without any problems.

Is there anything I can do? Has anyone experienced the same problems? I'd appreciate any help anyone can give me

 

@jmeyerson I never found the fix for the problem. In the end I just started fresh and copied all my files manually, with the exception of my iTunes library. With iTunes, I made a disc backup (File > Library > Back Up to Disc) from my old MacBook and restored from the backup on the new MBP.
