I have a FOXT2 and receive signalls from Rowridge on the Isle of Wight.
Using the Humax I am unable to get the Red Button to function.
Switching to TV direct and Red Button is ok
I also have a Humax 9300T in another room and this is also ok on Red Button.
Have done a retune on FoxT2 and no difference.
Would be interested if anyone else with a FOXT2 having the same problems getting Red Button to work?

What software version? Is this an HD-FOX T2 or an HDR-FOX T2?

My HDR Fox-T2 tuned to Sandy Heath;
BBC ONE (SD) briefly displays "Watch In HD (OK)" - pressing OK whilst this is onscreen selects "LCN" 101
Waiting until it times out, no "press red" is shown - I think that would only be displayed by an SD receiver. Pressing red does enter the BBCi app (teletext replacement).

Once on 101 BBC ONE HD, "press (red)" appears briefly, pressing red makes a "(blue) Menu" OSD appear.
Pressing blue brings up a menu "(blue) Close / Red button SD / Red button HD / Exit to BBC One"
Red button SD switches to LCN 301.
Red button HD shows the alternate HD stream, still on LCN 101.

So the HDR Fox-T2 does deal with the BBC red button services.
