Is this on DVD?

NO

Unfortunately, its not on DVD yet. I missed Season 1 and most of Season 2 so I would totally buy/rent this on DVD. It probably wouldn't cost too much to do a limited-release DVD transfer and it would be almost pure profit since the production costs have already been paid. I know lots of people would like to have all the seasons on DVD. They definitely should put a box set together of each season! In the meantime, I wish they would post episodes on a pay-per-download basis on tv.com or ipod.
