I sadly discovered today that nothing on my MythTV was recording, and even live TV was not viewable. "What gives?" I pondered as I poured through the logs.

Well, that didn't bode well. I sauntered into the data center (the nook under the stairs without adequate power, lighting or cooling) and found the power light on my HDHomeRun was blinking and worse, so was the light on the power supply. A quick google turned up a known failure with the power adapters on some versions of the HDHomeRun. Guess who was lucky enough to receive one of them?
So this post is just an FYI to anybody else who bought an HDHomeRun. The RMA process is dead simple, just enter your device ID, and they'll send you a replacement for free. But the question is, what are we going to do for 3-7 business days while we wait? Back to live TV again? Oh the humanity!
