I have a ViP211z with Winegard Pathway X2 dish for several months..no problem, but recently, I began noticing that the DVR playback would freeze and jump with some pixelation. When starting a DVR program, it can take up to a minute to actually start the playback. Also, the receiver is slow in responding to other remote commands on occasion (new batteries). When scrolling through the guide (up or down...or side to side), after 5-10 clicks, I have to wait a few seconds before continuing.
