It's not found by a full scan, nor by a "scan an existing transport and find any linked ones" option. I suspect Com7 on 746MHz will be out of band for my aerial so I'm not bothered about that.

Perhaps a bit late now, but a preamp before the splitter ought to
maintain the signal to noise ratio as well as boosting the level. Newer
tuners do this on-chip.
I forget which release you have been using, but a *lot* of work has gone
into DVB channel scanning recently.
