1. Is RAID the only solution for this purpose?<br>2. Is it possible to expand this RAID array later (insert an extra HD)?<br>3. My DVD collection will use a lot of HD space. Any suggestions on how<br>to reduce the file size (divX, ...)?

RAID is not really a backup solution. It only guards you against disk
failure. For example if you accidentally delete a file, it's gone! That
said I use software RAID5 myself for the reason that I don't want to
backup that amount of data, but I wouldn't like the idea that it's lost
because a drive died on me.<br>
Alternatives could be something like a NAS setup (e.g. FreeNAS) where
you rsync your files to. That way you have two copies so if you
accidentally delete one, the other's still there. Or an external USB
harddisk could be used as well.<br>
Expanding software RAID drives can be done apparently with recent 2.6
kernels. I haven't tried it myself, but read this feature is introduced
recently. Googling should confirm this.<br>
As you suggested converting your DVDs to DivX or the like is a way of
reducing disk space. An other idea is described in this thread:

trying it myself, but it's on my list of things to do on a rainy day.<br>
