I'm finally upgrading my old KnoppMyth box to new hardware and have put LinHES (new name of KnoppMyth) version R8 on it. Everything's been smooth up to the point where I try to "Fetch channels from listings source" for my three tuners (HDHomeRun Prime). Unfortunately, nothing happens. I can successfully retrieve my lineup from Schedules Direct (WOW Chicago Suburbs - Cable (60193) IL58819), and I've followed the steps both here:
http://www.mythtv.org/wiki/Configuring_MythTV_for_the_HDHomeRun_Prime
(mythTV 0.25 - what LinHES R8 uses)
and here:
http://www.mythtv.org/wiki?title=Configuring_MythTV_for_the_HDHomeRun_Prime&diff=54978&oldid=53554#Illustrated_Guide_.28.24.29
(mythTV 0.24-fixes - it tells you to create a Demo test recorder capture card and use that with the video source temporarily to get channel listings)
Here's the output when I run mythfilldatabase and only update channels:

Only when I have the dummy capture card set to use the input source do I get a successful download. However, no channels show up in the channel editor If it's just the HDHomeRun Prime tuners set to the input source, I get the message "DataDirect: Failed to get data: Download error" when running the same mythfilldatabase command above.
I chatted with Cecil, the creator of KnoppMyth/LinHES, and he said that he ran into the same issue himself, but it fixed itself eventually. I'm okay with waiting, but at the same time am anxious to get my new box up and running

Thanks very much!
