I don't know about all channels going HD, but I can tell you that Dish is being a real tool about trying to get me to give up my SD dual output receiver. I think it's the 322 model. (Non DVR, SD). Everytime I call (which has been often because we've been having issues with the HD receiver in the living room) they tell me I have to upgrade that receiver. I tell them, every time that it is working fine and is controlling two SD televisions, so I don't want to upgrade it. Then I get told they will not come out and do any work or anything else until I upgrade it.
Whatever. At this point, it is the principal of the matter. I almost upgraded until the rep told me I would be back on a contract. Um, no way in HELL is that happening. It took a supervisor and then the Customer Retention department to get that requirement overridden. Then I was told they were out of the HD dual receivers and only had the HD DVR dual receivers. I told them I didn't need DVR service and wasn't going to pay for it. So then they were going to wave the DVR fee for one year. Okay, I was still going to upgrade, but I was less and less happy about all of this. THEN the rep said, "Oh, we have to come out and change the dish on the house too."
Nope. Game over. That would be the third dish change by Dish in 5 years. That on top of the Directv dish still on the house (and the one I had taken down) and my Shaw satellite dish. My house is TINY. My roof is 'iffy" and at this rate, I've probably got enough holes in it to qualify for "swiss cheese" status, from satellite dishes alone!
I have to call Dish today. I am looking forward to the "...you have to upgrade your receiver" speech again. NOT.
