Quicker? YES. Easier? is it really that hard to insert a DVD and click a button?
this way he preserves his playlists and doesn't have to navigate through directories just to find their music. plus the OP didn't specify if they had a external HD and DVD's are CHEAP, just go to wall-greens and get a pack of 5 for 3 or 4 bucks.
No, it's really not that hard to insert 'multiple' DVDs and click several times, but to expand upon your question... is it really that hard to connect a hd and click a button?
If, as you suggest, the OP doesn't have an external HD, let's hope he has a DVD burner in his old PC running windows to burn his backups to. Then, you're right that it's cheaper, but still not easier due to the disk swapping required and time to burn then copy. But it could be a moot point, as lots of older PCs don't have DVD burners.
I think (just my opinion...

) it's easier (and quicker we both agree) with an external HD, because even if they're formatted for NTFS Windows instead of FAT32, formatted drives can at least be read by Macs, so they're basically cross-platform, and by 'backing up' his iTunes music from the PC to the external hard drive, he can then just plug the external HD into the MBP and restore onto his MBP hd and walk away. No waiting to swap dvd disks during burning and restoring. External hard drives are cheap and read/write much faster than burning/reading DVDs, making the whole process a piece of cake. This is assuming the OP can afford an external hd (I could be wrong, but he just bought a new MBP, so that's what I was thinking... )
Bottom line is, whatever way the OP chooses he can get done what he wants to do. Your option certainly is worth looking at as long as he can burn his original stuff to DVD for the transfer. Cheers.
