I experienced the mixing of the EA and WA last year. I canceled the sports pack (just in time i realized later) and ordered platinum HD. I got only ESPN HD and Encore HD. I was told that I had the dish pointed at the WA and needed to be upgraded. Paid to have it done, and found out that the tech put me on 110, 119, and 61.5. Had the 9900 channels to say congrats for being pointed at both sats. Through this board (before being a member) I find out that Dish was supposed to be giving me EPIX, E! HD, and the list goes on for about 10 to 15 HD channels. I call again, and was told the issue and was going to be charged to do it again. I was on my lunch break at work and basically to them to bug off with their fee. About a month goes by and I see through here and wikipedia that Dish launches EPIX2, and I believe Shorts HD to existing platinum HD customers. Now I'm furious. I get on with a CSR and don't quit until Dish agrees to replace my existing system with one that carries every channel that I am paying for. They want me to pay for the upgrade, I refuse citing that I already paid and their licensed tech didn't do the correct upgrade.
Basically, all I'm saying is that this is not as uncommon as one would think. Whoever said to look into either EA or WA and not a mix is dead on. First, my system did have that problem and only got resolved when I upgraded properly. Second, look into what you get through your packages, especially if you subscribe to platinum HD, because I bet you aren't getting everything that Dish is charging for.
