Options for itunes-filled disk? I haven't bought any TV shows on iTunes, but my boss has -- many. His MacBook Pro's 250GB disk is more than half filled with TV shows (mostly sitcoms for entertainment during travel). Most of the rest of the disk is filled with other stuff.

I see a couple options for clearing up some space currently occupied with TV shows:


buy a bigger disk (go to Apple store
and have them swap out the 250GB
model with the 500GB model)
move some of the tv shows to an external disk and help him restore when needed
backup itunes library and then just nuke


I've looked around on apple's site and on some other pages about backing up iTunes and it doesn't seem like #2 is easy to do from within iTunes. The full iTunes backup (#3) is more straightforward, but I think a full initial backup will take a couple dozen DVDs. 

The hurdle for buying a new disk is the cost plus the downtime while the Apple store is performing the installation and copy.

Are there other, better options that I've missed? Has anybody done any of my suggested options?
Regarding option number 1, the Apple Stores do not do hard drive upgrades.  You will need to take it to an authorized 3rd party or if it is a recent model MacBook Pro i would recommend just doing it yourself.  It is fairly easy and iFixit has a step by step guide on their site http://www.ifixit.com/Browse/Mac.  A 500gb hard drive should be relatively inexpensive on newegg.com or amazon.com, and i would also recommend going with a 7200rpm.  

I upgraded my late 2009 13" MacBook Pro to a 320gb 7200rpm Western Digital drive from newegg and have been pretty happy with the performance.

For option number 2, all you have to do is drag the tv show out of itunes and on to another drive.  Once it is transfered you can delete it from itunes.  Keep in mind that you probably want to keep a back up of the drive you transfer the shows to or else if that drive fails you have lost the content.
