Bob,
I run a satellite business here south of Houston. I sell quite a few DVR's, and HD receivers.
I'll tell you for a fact alot of people are disappointed with the HD and there new big screens. Want proof just watch a few channels of standard definition on a 56" or 65". I've got two people calling on me because there disappointed with there picture in standard definition. These are top of the line tv's Mitshubishi DLP and a Sony, but I see the problem with all models. Part of the problem is a 16:9 tv is 20% larger then a 4:3 tv. When enlarging a picture and then stretching it to fill the screen you are making it grainer like a photograph.
Most projection Tv's are adjusted to be displayed a store on a quality signal such as a DVD, or HD. They do a poor job of reproding standard definition and analog signals.
Check out this site for some help: they do a few mods to the TV to improve picture quality. I disconnect the SVM board and it made a big improvement . Quite a few people remove the glare screen.

Be sure to read the portion on ISF calibration.
You have to be very careful on burning your screen. The new channels FOX, and CNN with the logos staying on all the time will ruin your TV, same for video games, programming logos, etc...
On tv brands. I think a lot of people will agree that the Mitshubishi makes the best projection TV.
Myth or misperception #1 : Everything will eventually go high definition.
The only thing that the FCC has mandated is that over the air broadcasters swith from an analog signal to a digital signal. With the digital signal they will have the capability to broadcast in High definition. That doesn't mean that every show and channel will be in High def.
You think reruns are bad on regular TV. Just wait to you get VOOM. be prepaired to watch the same thing every few days. The other down side of Voom is no DVR.
If I only had a choice of a DVR or HD box. I would take DVR everytime. When you don't watch much TV it is nice to watch what you want when you do.
The problem is that the TV manufactures and technology are ahead of the wide spread availablitity of high definition programing. The TV's stores want to sell you a high profit TV they never tell customers the whole story.
If your only wanting to spend $30-$40 a month I feel your wasting your time looking at HD.
for the post above DVR recievers are availabe with over 250 hours of recording.
