Backing Up I-Tunes downloaded TV shows?

[jman220]

I don't have an IPOD, but i've downloaded a few episodes of bstar galactica via itunes to my laptop. I now need to format and cannot figure out how to backup the episodes, itunes only allows me to burn music to cds. I don't want to lose them, can anyone help? I tried clicking and dragging the files elsewhere, but I'm not sure this will work. Thanks.
