I tried two years ago to upgrade from basic/standard cable to digital w/DVR, it lasted about three weeks or so, I got so many "channel unavailable" messages it was ridiculous. Bright house said at time it was faulty DVR, many reboots, many "signal refresh" from bright house, as well as me initiating from bright house website, with no luck. I replaced DVR twice, and still no change. It did not seem plausible that it was a technical issue at my end, but bright house insisted. It just did not make sense to me, so I just decided to go back to basic/standard service. So cut to about a month ago, bright house informs it will no longer have analog channels, so an upgrade was a necessity. So I was willing to try again, and went with upgrade to DVR, and I believe all of the movie channels. Things were fine for about two weeks, then started getting NUMEROUS "channel unavailable" messages again. So went to research this on internet, which led me to this site, and explanation of SDV, and the seas parted, lol. Some tech specs a bit beyond me, but made damn good sense. So it seems bright house does not yet have an adequate platform/system? to deliver all channels to customers who request them. It sounds like this can be corrected if bright house would invest in an upgrade to its platform/system? so that it can deliver signal to all those customers who request it. So is upgrade in progress? How much longer will it take? I have sent repeated emails to bright house, asking about SDV, and is it true that they are limited as to how many customers can view whatever channel they choose. Bright house completely ignores the question, and gives same old story of malfunctioning DVR, or some technical issue at my end requiring service tech visit. Frustrating does not describe it well enough. So is bright house upgrade to all digital also going to resolve this issue of unavailable channels? By the way I am in Orlando, Fl area. Thanks for any info, feedback you can give.
