My family has been reporting some errors when watching STB channels. I use the Hauppauge Colossus. Today I had some time to troubleshoot. After trying a few basic things (checking drivers, etc), I decided to start rolling back from 19.0.137. I tried 19.0.136 and I get the same things. When I tried 19.0.125, everything works again. I noticed in the release notes that something changed for STB box support. I can recreate this and send a log if will help.
The error I am seeing is something about the device being in use, but it is showing idle in the status window.
