I want to get my Hopper installed ASAP and I'm wondering how I can migrate my current recordings to the Hopper. Can I just plug in an EHD (I don't usually use one), move the programming over, then copy it back to the Hopper once the install is done? I'd rather not use an EHD permanently if I can help it. I know I'll have to set up all my timers again but that I can deal with.
