Hi Guys, New to HD and trying to comprehend the whole recording thing. I have just made an appointment for upgrade to HD. They are coming tomorrow to swap out my duel dvr with a vip722k and see if they need to do other stuff with the dish and stuff. I know the dvr has 500g. From what I have read it says 55 hours hd, 350?SD Is this either or, or a combination of both. In other words if everything is recorded in HD would you only have 55 hours recording time and nothing else? Also can you designate somehow to either record in HD or SD . Like are the channels listed twice, once for the SD and once for the HD or do they have different numbers? Is it an options screen. I can usually understand the new stuff but I can't find a screenshot of the guide of the 722k to answer some of these questions. Thanks for the help, you guys have been very helpful to me in the past, I'm sure this time will be no different.
