The 830 has:Follow up to my post of 29 May.
Strange events. I'm now running a 630 which had been in my bedroom as my primary receiver. So, I connected my "bad" 630 in the bedroom to see what would happen. It appeared to have the same problem as before, and it had not "booted up" when I went to sleep. But, when I woke up in the morning it was up and running like normal. I tried a reboot to see if it was indeed operating like normal (ok, I'm stupid). It had the same result - the boot sequence took a number of hours. I still think there's probably a hard drive problem, but at least I have a way of watching the recordings I hadn't watched before (for now).
My guess is it will fully fail in the near future. The only solution would probably be a hard drive replacement, but then I'd still have a ten (or more) year old receiver. At this point I'm thinking of replacing it with an 830. Are there any flaws in my thinking? (I'm assuming the 830 has all the kinks worked out by now.)
No front panel clock
No front panel "Presently Recording" indicator
No front panel "Satellite Signal lost" indicator
No rear "Component" output
If those are not important for you then the 830 would be the logical choice.
