Well as a last step to my ultimate HTPC, I ordered and received the HDHomerun which I planned on using with an OTA antenna and mac mini. I was all excited to get it up and running and then the excitement quickly ended. For some reason, I can not get a consistent picture despite constant sound from the TV show. It seems as soon as I change a channel or watch a particular show for a short period of time, I will get a blue screen saying "no signal available". When I look in the options at the signal STRENGH it says 100%. It seems like the HDHomerun is dropping the signal because when I look at the signal QUALITY both tuners (0 and 1) show around 80% and then when I get the "no signal is available" error one of the tuners shows 0% while the other remains around 80%. BTW I have a completely wired connection between the HDHomerun, Airport Extreme and Mac. Has anyone else run into this problem and have found a remedy. Prior to setting up the HDHomerun, I was a running the same OTA antenna into a TiVo and was getting crystal clear reception with none of the above problems. Any suggestions? Thanks.
