For backup - DVD vs external HD - it mainly depends on how many shows you plan to have/keep. If you only download a show or 2 a month, HD would probably be ok. But if you download 20 shows a month, you'll be buying a lot of hard drives.

Personally, I'm always finding something to download. So, I download to HD. Then as I get a chance, I backup to DVD as data and burn a copy to listen to/watch, and delete off. After a little over 2 years with BT, I'm up to 90 backup DVDs and still have 2 full 160 GB HDs (both Western Digital, 1 internal, 1 external).
