And, even then, what are we going to need it for? What is its use? With a DVD-9, we can put a full length high quality movie and sound track. What more demanding consumer application is there?
If we want to upgrade something, let's upgrade from MPG2 to MPG4. That will allow a DVD-9 to store a huge amount of high quality video.
I recently purchased a Philips DVP-642 DVD player and I was happily surprised to find out that it does a few cute tricks. Not only does it play CDs of MPG1L3 audio, VCDs and SVCDs, but it will play CD-ROMs full of MP4 files. So, I can get a DVDs worth of video on a CD with very little quality loss--for normal definition video/audio. Very nice. :) Now, a DVD full of MP4 files is a lot of video. I guess I need to go find a tool to convert my DVDs to MP4 files. :)
