Unable to change channels with program guide with a single analog tuner.

[paperjams@…]

While watching live-tv, it's not possible to change channels with the program guide when using a single analog tuner.

• When changing channels it gives the message that all tuners are busy.
• Changing channels by browsing or typing in the number works as expected.

Also after adding another analog tuner, changing channels with the program guide worked but it alternates between the two tuners.

I can add to this. I'm using dual tuner and if one of them is recording and the other one is watching live TV then I experience same problem.

Fixes #10566. Reverts part of 3a51b833e to improve channel changes.

The first half of 3a51b833e looks like a bug (the new condition means
the following "else if" branch is never taken). Removing it stops
guide-based channel changes from being forced onto a different tuner.

Note: this fix exposes another problem with guide-based channel
changes - you can't switch to a different tuner in the current input
group. Fix is in progress.
