They'd replace it even if it wasn't giving you problems. Call and ask.
Same thing here ( except they have upgraded me twice for free ) , I have insurance but the 10-250 will not dien6nfg said:I am in the same boat, my HR10-250 just died (disk bad). I got a free HR20 back in the spring to replace the HR10, but I said I wanted to keep the HR10 active in another room, and they said fine.
Since the HR10 is not the primary DVR on the account, and it was already "replaced" for free once, I don't know what my options are on getting another HR2x. Free would be nice (including an AM21, I use OTA), but I don't really know what to expect. And no, don't have insurance. The HR10 is owned however if this makes any difference to the outcome.
