True, but (for me) it will be useful to designate a channel as HD and thus set all programs as such unless
the XMLTV/EPG says otherwise.

I sometime record a movie on one channel in SD, then later it is shown in HD on an unrelated channel.
In this case I set my schedule to filter "high definition" so as to ignore any repeat of the SD version.
I finally inactivate the schedule after I have the HD (and delete the SD).

Not on my f30, but it is always here:

Actually, in my case I am very sure that the HD channels have only HD programs of interest.
