I seem to remember this question being asked before - but I could not find a post on it.
Should MC be able to tune into an OTA channel when/if the guide data is missing?
I noticed last night, that channel 43.3 and 2.2 had no guide data displayed ( I have a post about getting guide data from multiple sources to fix this). So, last night, I could see that the channel is there/listed however I move down the channel list, channel-by-channel, MC just skips over these two channels (missing the guide data).
If it was possible, it would be nice if the channel still played even when the guide is empty.
Of course, I wouldn't know what is showing by looking a the guide, but at least then I would be able to tune in and perhaps see if it is something I care to watch.
