A tech came to my place recently and ended up replacing my HR20 (with an HR23 so nothing great) - one of the tuners was broken, so the HR20 was still bootable, it just couldn't record. When I told him I had a ton of recordings on my HR20 and didn't want to lose them, he told me - as in "hint hint" - that if a customer insisted they owned the DVR and refused to give it up to him, he'd just put that on his form and leave it with me. So that's what happened. While I can't access any of my old series links and obviously can't record anything on the old HR20, I can still watch everything I've already recorded. Plus you can set it up such that the two DVRs receive different remote codes so there's no overlap between the two. It was nice of the guy to mention it so I thought I'd pass it along here.
