I have a couple of issues I would like to find answers for. Would like to not have to open every post trying to find which post will help me find these answers. I have a 622 dvr, the hdmi has stopped working, It seems to be a problem with all 622's. Has anyone found an answer other then having Dishnetwork send out a replacement? I also would like to replace the internal hard drive, I have read that there are 3 500 gig drives that are compatible but, they aren't still being made. Has anyone tried to install a 1 TB drive? I was looking at a Wd black cavier, which is the newer version of the hard drive that was the recommended replacement.
