I'm not sure it's a bug. I have a usb Genpix Sky walker and works well, but sometimes not open the channels have to re-enter the channel and is seen again. I have tried several settings like tune repeats and input buffer but is always the same warning. when warning appear wont open the select channel. Any idea what it could be or how to solve. This is the log.
