Having past the half century mark a bit ahead of you I admit to a certain amount of ornoryness and crankiness that comes along with that milestone(?). That said, I should have been more accurate in my posts. Rather than saying "a questionably designed and executed DVR (mini computer with a HD) with a very simple power supply" I should have said "a problematic DVR without a terribly sophisticated power supply". I've been inside an R15 and the power supply, and entire unit, is remarkably cost effective... if you get my drift . The OP was referring to a previous thread where I posted my specific experiences with PVRs- DVRs and the annoyances of losing recordings and guide info because of power drops and brown-outs. I solved these problems by putting these PVR-DVR units on a small (and cost effective) UPS. Nothing special, no sine wave/square wave power, just a (very) short term battery backup in effect. That solved the problems I was having. I've done the same for others and those problems were also solved for them. That is the first hand experience, cause, and solution I posted in that previous thread. I don't apply scholarly reflection when faced with a problem, I'm a tech. I do "how" problems, not "why" problems. I see the problem, I identify the cause, and I form a solution. That's what I get paid for. That's what is expected of me and that's what I do. The philosophy of the execcise doesn't concern me. I get paid for results. Seems to me that spending $40 is a modest enough expense to find out if that cheap UPS will solve the problems for you that it does for me. As far as I can see, putting an R15 on a small UPS will have no negative effects if the UPS and its internal battery are operating properly AND if you buy a brand name like APC they include a free insurance policy that will pay for damage to protected equipment if that UPS fails to protect devices plugged into it. With respect, I believe you suffer each and every problem you post about with your DTV DVRs and I defend your right to post as often and as loud as you like BUT, I have none of those problems with my two R15s. Maybe, by blind luck, I stumbled on something that mitigates some of those R15 problems or maybe I know what I'm doing, or maybe the DTV gods just smile on my two R15s. Whatever the reason, my R15s work reliably and I'll accept that and watch (and record) TV. Bottom line, like we said in the school yard 45+ years ago... mine works, how's yours?
