Hi!

After the set scans the available channels, is there any way to
watch a channel, analog, that it hasn't sensed?

Digital TV introduced the concept of "subchannels" to ordinary
broadcast TV. These are expressed as ".1, .2 .3" and so on. So if you
have a DTV station on, say, channel 12, any of its broadcasts could be
accessed by typing in "1 2 . 1" on the remote control. Somewhere your
remote should have a . key.

On any TVs I've seen that had a combination digital/analog tuner, the
"subchannel" concept was retroactively applied to the old analog
broadcast channels, so they are entered in with a .0 after the channel
number. This means that if you have an analog station on channel 12,
you might need to type in "1 2 . 0" to get at it.
