Advertisements Tried to cancel my Dish account tonight (8 year customer, but cable internet + satelite was just wearing me down). Anyways, the account rep mentioned a big change coming end of Mar 2006 regarding Dish's HD programming/hardware. Anybody know what this may be? I currently have an older Dish 500 dish (and no HD). I asked if I wouldn't need a new dish installed for HD and she said not with the coming changes. That peaked my interest enough to stay subscribed a couple more months. I also asked if the change was a move to MPEG4. She said their latest HD receiver already uses MPEG4. Did not know that. Anybody have info, or point me to a more appropriate forum?
