For those having this trouble here is what I did to fix the issue...
Go to the HDHomeRun setup and block any channels that have a channel number of 1000 or more. For me it was all the music channels.
To block the channel look for the channel list where you mark favorites and click the star until it turns into an "X".
I read the Nick is working on a fix for this but until that release is out, this fix seems to work for me to get the app working on the Roku.
