Chris: Unplug the box, leave it for a few minutes, and plug it back in.
This problem was first reported on Humax boxes. My hypothesis is that the BBC have changed the program ID for the code that pops up the 'Press Red' indicator - reusing a program ID previously used for 'return to last transmission' when you press TEXT to exit the interactive stream. They probably didn't think anyone's box had been on long enough to still have it cached.
Or, they've changed the program and it's not compatible with some MHEG interpreters, but that wouldn't explain why power-cycling the box is working for so many people.
It is recommended that you do a complete retune from scratch at switchover dates, but I can't see how to do this.
I did find this method of doing a software reset:

That whole thread might be useful. (RG47SH)

To Dave of Ely, I have the same problem with our Philips TV - digital text has stopped working, but it continues to work fine on our non Phillips TV in the bedroom

Many thanks Mike
I found out how to do a factory reset of the Sony box and that seems to have solved the problem.

Gwyn Jones: Doing a "first time installation" usually fixes the digital text problem.

Nottingham east. Immediately after midnight on 13/4, i.e. @ 0.01 on 13th, lost all itv channels except itv4, lost all 5 channels. Easier to say what we have retained. Spent almost £200 on digital arial 18 months ago even though Govt said the changeover would mean no extra cost.
Receive channels via Panasonic DMR Freeview Box.

6.30 everything on Sandy Heath including HD channels.... went back to bed.
On Humax HD2 needed to auto search then manual search on that order to force Sandy Heath channels in correct slots else back on the aerial issue. Humax idiosyncratic as probably all boxes in their own way.

Tell: *ALL* equipment requires a "first time installation" at the final stage of switchover, not just Humax.
