My UPN station will likly NEVER be HD. Unless they find a way of broadcasting the CBS primetime and the UPN primetime at the same time both in HD or shift UPN primetime to another time of day. The way may very well be 720p at some lower bitrate. It is a business decision that the local station will need to make.
Each television provider must make their business decisions. DirecTV has made theirs, Echostar is making theirs. If your local cable company does HD then you have a third option.
As far as visible glitches ... I watch OTA HD in 'glorious 1080i' that isn't perfect. I wonder if the PQ issues that can be found only when some expert gives you a precice flicker to look for is one on the inherant errors in transmitting a digital signal at any rate. Sending 1920x1080i does not guarantee a perfect picture.
And back to the original complaints ... IIRC: From the first week that Voom was on Echostar they were broadcasting six of the 10 channels in 1280x1080i. The sky apparently fell when the other four channels were changed to 1280x1080i. Why? Were the six channels junk where nobody cared about the conversion or were people living under the unrealistic assumption that for some magic reason all of Voom would be 'upgraded' to 1920x1080i ? If you have been living under that assumption, why? Does the history of E* tell you that they are a company that gives MORE bandwidth to a channel over time or that they are a company that tries to get as many channels as they can get away with on their bandwidth?
There are some unrealistic expectations at play here.
The changes to CBS HD were observed when E* turned off the old CBS-HD East feed from Echostar3 and turned on the new CBS-HD East feed from Rainbow1. The new CBS-HD being part of a mux that will be delivering LIL-HD to the New York City DMA. Few know how long the 'new' feed has been testing in 720p - and no one is saying - but the 720p CBS-HD feed was not made available to customers until AFTER the Voom downrezzing complaints began, and in many of those complaints it was suggested that 1280x720p would be better than 1280x1080i. Which makes it appear that E* was listening to the complaints, just not choosing the real answer that the majority wanted.
The "CBS is now being converted to 720p" thread is a recent thread started long after the Voom complaints started. As far as I was aware, the changes to CBS happened after the complaints about Voom. IF the change to CBS happened prior to the Voom changes, I wonder why no one complained?
