I found this in the BEO4 user manual (cut & pasted). Download the BEO4 userguide from B&O and it should tell you how to change the user VIDEO OPTION.
Hopefully that may help.

Other options than
those listed here may
appear in the display
when you select
VIDEO? or AUDIO?.
These other options are
listed below. Refer to
the Beo4 lexicon on
our web-side for
further information.
In order to use teletext
on a television you have
set to Option 4, you
must set up Beo4 to
‘VIDEO 3’, but this
limits the Beo4
functions that can be
used with televisions
set to other Options.
For further information,
refer to the Guide for
the television.
