The DISH Network HDTV DVR satellite receiver model ViP 622 is a high definition satellite receiver that is capable of recording approximately 25 hours of high definition or 180 hours of programming on a 250GB hard-drive.  This is the replacement model for last year's model 942 HD PVR.  While having similar features from last year's model, the 622 is now capable of receiving MPEG-4 video signals as well.  What that means to you -- the consumer/end-user -- is that it allows you to receive more HD channels, including all of the VOOM HD channels (now totaling 15), than before.  While older systems used MPEG2 encoding that takes up a lot of bandwidth, MPEG4 encoding takes substantially less thereby allowing more signals (resulting in more channels for users).
