Im having lagg issues between what I press on my remote and how long it takes the hopper to process the command. I only get this error about 50% of the time and it usually happens when im in the menu system or when I use the FF button. I reset the remote changed the batteries im only 5 feet from unit when using remote no heat nearby or weird RF signals in my house. From what I can figure out DISH upgraded their processor from 750mhz to 1.3ghz in Feb of 2014. My experience with this kind of secret upgrade usually can be figured out by the model number however dish CS didnt have any way of figuring out which version I have but worse if I ask for a replacement from DISH I will not be able to figure out which chip I got. Now in the past the way I got the exact receiver I wanted was to call down to the warehouse people and talk to them directly. I dont want to have to backup my DVR and deal with shipping if im just going to get another unit that is identical to my unit. One way I know to get the faster chip is to order it with the sling built in that will guarantee the chip upgrade however I dont use the sling option I use the internet for off line viewing. Does anyone have an idea how to get the model information on the newer units?
