So this brings something up that I have wondered about. Why couldn't someone have developed a high speed tape reader- one that would pull the digital information off a DV Tape at 4 x speed, or something like that. Is it a physical limitation on the tape itself, or a technical issue with the data stream ? Any geeks out there know why ?

Even though the required video scaling always looks worse than if they'd stuck with a CRT TV. But convenience is a big factor, and the low profile of flat panels is very convenient and probably the biggest selling point.

Same goes for buyers of computer LCD monitors vs. CRT - it's just more convenient, you get all that desk space back.

While you're correct on your points, there is high def content on Cable TV as well as high def PVRs. Some HD channels are fantastic (NatGeo, ESPN), but most of the movie channels are blocky as well as good-ol-DVD-data. I'm planning to ditch cable and go with an antenna (ATSC), as that worked very well in my previous house. There are some HD channels that look HD and require no monthly subcription. Sometime in 2009, your neighbor will notice that his TV looks better .

As for a CRT TV, I have a Sony WEGA 40" that is 305 lbs. The good part about that is that it's nearly theft proof as you need two strong theives to carry it to the truck.

I remember Pinnacle Systems polling for a 2x DV reader device. Some DVCAM modes on some recorders operate the tape at a slightly higher speed. There is probably a good reason for the DV tape data rate: that's all that tape technology can do reliably, both with respect to data accuracy and medium integrity.
