Tuner Setup, inconsistencies between ET10K and Ultimo4K

[ccs]

Not a problem as such, but I'd like to understand why 2 boxes differ so much when setting up tuners.

Xtrend ET10K attachment 1 shows the tuners and attachment 2 shows that tuner A, say, can be configured as T2 or C.

No issues with that.

VU+ Ultimo4K, slot one has a dual T2 tuner, slot 3 has a dual hybrid T2/C tuner. (That's how it was purchased.)

Attachment 3 shows the tuners. The BCM3466 is, as far as I'm aware a dual T2 tuner, not a combined T2/C tuner.
The TT3L10 is the dual hybrid T2/C tuner.

Attachment 4 shows the dialogue when the BCM3466 tuner A is selected. Not the same as the ET10K dialogue.
Despite this, I can change the tuner type to C with the left/right arrows the way tuner setup used to work.
(And, as an aside, the red close button leaves me with the last tuner type selected not the original one.)

If I select Tuner C, TT3L10, I cannot change the tuner type, even though it is a hybrid tuner. All I can do is disable it or leave it as T2.

Maybe slot 1 becomes tuners C and D, and slot 3 becomes tuners A and B, but it still doesn't explain everything.

This commit suggests the BCM3466 is a dual T2, (although there's also a reference to the TT3L10).

This is what a BCM3466 tuner looked like a while ago.....

All that stuff comes from the procs. So tuner description, etc, is coming from the drivers.

.... thanks, a bit more digging suggests that the driver update dated 2019.04.24 (the last driver update for the Ultimo4k, as it happens) added DVB-C capability to the BCM3466 tuner for some reason, although it is still marketed as a dual DVB-T2 tuner only.

Why does the tuner setup interface differ between the ET10K and the Ultimo4k, the latter still uses the "old" format which was updated a year or so ago (attachment 2 in post #1)?
