That seems to have resolved most of the issues. The config program still crashed on the initial run but it managed to update the configuration as I'm now showing 45 channels (when it was 0 before). I was able to watch live tv from my iOS device just fine, but the roku app still wouldn't find anything. Perhaps it's just an internal network issue, but I'm glad to see it working this much so far!! Thanks again Nick!
