Blu-ray and HD DVD are completely different in physical construction and their data architectures are also different. DVD+/-R differ only in their address systems and in some minor copy protection details.

Commercial Blu-ray movies were initially 25GB in MPEG-2 and were inferior to the 30GB HD DVD movies using more advanced encoding. Now Sony is using the same advanced encoding and producing more 50GB discs and very poor yields and very high cost. The dual layer Blu-ray medium is not easy to make.

Some Blu-ray DL recorders and drives are available. HD DVD recorders and drives are far behind Blu-ray devices.

Actually the latest yield figures are improving at their Indiana facility. They're reporting BD50 yields consistently b/w 75 - 79 percent. BD25 yields are consistently at 85 percent approaching parity with DVD production.

I'm so happy for (and suspicious of) Sony. The other non-Sony plants are at 20% yield for BD50. That's a lot of plastic for regrind.

It is not possible to rip Blu-ray movies and record them onto Blu-ray discs because of all the protection schemes imposed on the discs. In time it may become possible, but it will still be difficult and questionable whether or not it's even worth doing. (You'll need a display larger than 1.3 diagonal meters/50 diagonal inches to begin to see the difference between HD video and good upscaled DVD.)

I'd wait a bit. Panasonic just announced high definition onto DVDs using new encoding methods. There never has been a truly good reason to abandon the red laser for the blue laser in order to get high definition video. The real reason was the lapse of royalties and patents and the hope that new players/recorders and disc formats based on blue lasers would force people to shell out money once again to have "Bambi" in the "best" quality. Now that it is obvious that the public is not jumping through hoops to get blue laser equipment, Panasonic, Toshiba, and others are exploring new ways to use the DVD format.
