Hi,

Anyone had an experience with these double density discs, either with burning software and/or dvd players?

cheers

They can only be burned/read (at 1.3Gb) with a particular double density burner. So basically they are useless.

gary_cheshire -- To expand on Craig's answer a bit:

These "double-density" CD's can only be burned in one particular model of CD-RW drive -- which, of course, only Sony makes. They can also only be read in that particular model of CD-RW drive -- no other CD-ROM, CD-RW, or DVD-ROM drive can read them, not even other models also made by Sony, and no set-top DVD players can either. So, essentially, it would be about like recording your video to an Iomega Jaz cartridge, only with even less portability and usefulness.

What Sony was thinking when they rolled this thing out, I can't imagine... but it was basically dead on arrival, since no one who needed that kind of storage was willing to put up with the lack of compatibility or the premium price tag, so it's a dead end. The only reason Sony continues to support it, I'm sure, is because of the same sheer bloody-mindedness that kept them supporting Beta for years after it was clear that the format war was over, and they'd lost.

Sony at least has one partner in this DD_CD.
It is Sony's old friend, Phillips.

I saw the double_density CD spec and Logo at Phillips Web site.

I think the current trend is hybrid CD.
That is a DVD layer under a CD layer.
Sony's SACD is in this format.
I heard it work with both CD and DVD players, ( of course you need
to get Sony equipment to read the DVD layer ).

Thanks for your replies.

So the max capacity is 800mb cd-r/rw!

Will any form of file compression work on avi's better than winzip etc

Or is it possible to reduce the video quality of the avi files

cheers

Depends on .avi. (there is no such thing as .avi compression) I think, You mean DivX? Can't be compressed with other methods. Can of course compressed more with video tools with the cost of quality.

Not quite true, you can get discs that support 90 or 99 minute overburning. However, you need to check that your burner will support them and that your DVD player will read them. The most my Pioneer 636 will read is 88 minutes, then it starts to skip.

ack, don't do that. just use a codec to compress your video
