Recordable DVD’s are just not big enough to hold anything except one highly compressed movie. If you have spent time and invested in a good big screen, then this would be counter to your goals.

With a Blu-Ray burner it would take a dual layer disk recording (50 gigs) to even get close to a Mediacorder at 80 Gigs. But as with all optical technologies  they can and do fail during the “Burn” operation. Currently a blank dual layer disc is around 40 dollars. If BD disks follow the same failure rate as a DVD. This would be 1 out of 10 burns will result in a ruined disk. One failed disk and your out the money plus all the data you put on it previously. Unlike optical technology, Mediacorder’s are completely erasable and read/write. Do not require any burning operation, and you can never “Ruin” a cartridge during writing. A Mediacorder cartridge can be completely rewritten as many times as you like.
