So thinking of upgrading my VIP 622 to a VIP 722 just for the extra storage. Since it seems that's the only upgrade the 722 offers over the 622. Problem is, I don't want to lose all my DVR shows on my current 622. Is there any way to transfer your shows from the old receiver to the new receiver? Is it possible for the techs to do that when they show up and replace the receiver? Or is the only way to enable hard drive storage, attach a hard drive, transfer the shows over to the hard drive, and then transfer them back to the 722 when I have that installed? Haven't messed with external hard drives attached to my receiver yet, so I'm not so sure.
