I've been renting a Comcast DVR for 9 months waiting to see what DISH and D* are going to offer in the way of HD.
You are right - in this case no news was bad news. The D* reps said, flat out, no new HD - just a bunch of locals will be added wasting yet more bandwidth. The excuse is, people want their locals delivered by what ever provider they use - be it cable or sat.
The HD DVR (MPEG4) to get any of the new channels that may be added won't be out for several months. They are selling a plain MPEG4 box in the meantime.
DISH isn't adding anything substantial in the way of HD except for ESPN2 and a few of the old VOOM channels. They don't offer any of the premium HD channels except for HBO and SHO. Both D* and DISH have only one HD PPV channel.
Bottom line - since neither DISH or D*aren't really progressing w. HD - might just uupgrade our BEV (Canadian DBS) box to the DVR. Unlike the two U.S. companies, BEV carries HD PBS, WB, UPN. Even our local Comcast cable doesn't carry all the local HD - altho they do carry PBS HD. Comcast has no real HD PPV channel. BEV has 4 carrying mostly new movies.
