HD Recorder Can Use Standard DVDs 154
Stonent1 writes "Early next month Panasonic is going to release a DVD recorder that can store HD content on standard DVDs. The new device is expected to be a boon for the backer of the Blu-ray format; Blu-ray uses discs several times more expensive than standard DVD media. While the DVD discs won't have the capacity of a Blu-ray disc, the content will be of similar visual quality. 'The company said it will start selling three models of new DVD recorders capable of recording full HD programs on conventional DVD discs on November 1. The high-end model with a 500-gigabyte hard disk drive is likely to sell for 130,000 yen, Matsushita said.'" Update: 10/02 16:18 GMT by Z : Rewritten to clarify.

Until they release more specs I can only speculate, but the press release makes it obvious enough - This simply contains a perfectly ordinary DVD burner, to which it writes MPEG-4 data on a normal DVD using the FS layout expected by BR drives.
Just as you can burn a DVD filesystem to a CD, you can just as easily burn a BR or HD filesystem to a DVD. They simply don't hold as much, requiring either loss of quality or limited duration (or both).
Now, why anyone would want to buy a recorder that costs more than the difference in price of recordable discs over the practical lifetime of that player while burning only ultra-low quality content, ya got me. The coolness factor, I guess? Personally, I plan to wait for dual-format next-gen burners and for one or the other's writeable discs to drop a tolerable price.

This seems likely. However, Note that while the DVD file system on a cd is legal, it is not maditory for the devices to support it. Some devices do (including computers generally), although a fair number of devices do not.

They do. However, Blu-Ray players also have the correct laser so that they can read conventional DVDs and CDs. I'm not sure if they do this with a totally separate diode, or if they have a diode that can be switched between two different wavelengths, or what. But it would be pretty dumb to make a "next gen" video disc player that wasn't backwards compatible.

Very generally speaking, yes, they will, because the decoders are identical. The difference is in the way that the compression is implemented, not in the format of the data.
Codecs can be really messed up like this. We tend to think of a codec as being a compression format, but it is really the software. Any two codecs that have the end compression format can decode the results of each other. Both DivX and xvid yeild MPEG-4 ASP encoded video. That said, some DivX decoders are broken, failing to support some parts of the MPEG-4 ASP format. These may have trouble with xvid video.

Yes, people want to know if a given disc will work with their player, which is one reason why we need medium formats. Yet in a relatively free market, you'd see many multi-medium drives that work with almost anything (see most $49 DVD players today), so I'm guessing the number one reason for making new medium formats is control and DRM.
