I've got some VHS taped programs that are 90 minutes to 2 hours in length. Some of them are study tapes. Last week while hitting the play button, I accidentally hit record and lost 21 seconds of an almost impossible to replace video!

This made me think that I should start turning these more valuable tapes into DVDs. But here's the problem. Uncompressed content runs something like 13GB per hour. But I haven't seen any blank media that goes above 10GB. Obviously such media exists since Blockbuster is easily getting 2 hour plus movies on their disks.

Can you guys tell me where I might purchase those kind of blank DVDs so that I don't have to break up my programs between multiple disks?

At the moment, the only blank media available is 4.7GB single-layer - the actual data capacity varying between 4479MB and 4490MB depending on brand. Fitting more than this on a single recording layer is not supported by the DVD standards.

However, dual-layer media is coming, which will allow nearly double that capacity. But to use the new media, you'll need a brand new DVD-R drive or DVD recorder. Drives for computers are on the way, but I have seen no announcements about dual-layered DVD recorders yet. The technology is still fery much in its infancy and problems are expected, especially with readability by stand-alone consumer DVD players.

Bear in mind that even dual-layer recordable media will only get you a shade over 8GB. For 10GB and above you'll have to wait for the next big thing - "Blu-Ray" recordable discs.

DVD-Video was never designed to contain uncompressed digital video. If you capture your VHS tapes well and encode them into MPEG files with care, there's no reason why you couldn't get 2 hours of video onto a currently-available single-layer DVD without any noticeable loss of quality.

Hope all this helps; I can point you to a few sites with info if you're curious about the new dual-layer recordables.

(And yes, most commercially-manufactured DVD movies you find at Blockbuster are pressed as dual-layered DVDs, as this format has been around for years for manufactured or "pressed" discs)

Someone correct me if I'm wrong, but I believe I read in the LA Times over the past five or six days that dual layer capable recorders are going to be released to the general market by Pioneer and (I think also) Panasonic starting in August. If so, that should get a pretty good supply into the market by Christmas.

DVD-V at VHS quality can run for 4-6 hours per layer. If you don't want to edit and other stuf on a computer, just get yourself a Sony DVD recorder and leave it rolling as you watch.
