I think that's the problem. They weren't focusing on the low-end consumer when they had Voom, but then they got rid of it and put up channels that weren't even full-time HD. Now they're still turning away high-end customers by not fixing the LIL HD audio problem. (Here's a hint: it wasn't always like that, so REVERT TO THE PRIOR SOFTWARE so your customers can USE WHAT THEY'RE PAYING FOR and then use a test channel to work on the problem.)
I'd hesitate to say that having Voom made them more appealing to higher end customers. Maybe at the beginning when that made their HD channel count higher, but not this year with the multitude of traditional channels offering HD feeds.
I think Dish simultaneously goes for high end and lower end. Problem is, higher end customers don't like being with a company that goes for the lower end. This is largely a marketing problem. And having a blue collar entertainer like Frank Caliendo be your spokesman isn't helping.
And I've had audio drops on my 622 for a while. Reverting to prior software without issues probably will take us pack to the days before EHD support, and things like that.
