I accidentally entered a channel that doesn't exist on one of my tuners (tuner 4 I believe). By doesn't exist, I mean a channel like 80028 that is not part of the comcast lineup and not a channel that exists but I don't have a subscription. I can no longer change the channel on that tuner. Every time I try it changes the channel on a different tuner. I tried to work around this by recording something on all 5 other tuners, switching to the tuner that is tuned to the inaccessible channel and then trying to change the channel. No luck, I get a message that it has to stop recording on the last tuner I used to change channels. Is there any way to get around this without rebooting the roamio? I'll note the only reason I am reluctant to reboot the roamio is that I usually get a C133 error every time I reboot that lasts for a couple days. Plus I was currently at 5+ working tuners (the 6th tuner only works for some channels and I have it tuned to a channel I frequently watch).
