Try running mythfrontend with '-v mheg,extra' and post me a link to the
log and I'll see if there's an obvious problem.

The iplayer.diff patch is designed to add 'interaction channel' i.e.
iPlayer capability and is not any kind of bug fix or update.  The patch
should be applied to current git fixes/0.24.  Make sure that you have
the latest patch, it was last updated on 6th September.

Try this:
# skip this if you already have a myth repo
git clone git://github.com/MythTV/mythtv.git

wget http://www.softsystem.co.uk/download/mythtv/iplayer.diff
cd mythtv
git checkout fixes/0.24
git clean -fxd .
git pull
patch -p1 < ../iplayer.diff

If the patch still fails then your repo is probably corrupt.

Then run ./configure and make as normal.

After the patch is applied you must provide http connectivity from the
box to the BBC.  Without a connection the MHEG code can take 60 seconds
to timeout before displaying the old 'Red button' logo.  To disable the
interaction channel set this environment variable:

It may be a technical problem with the Sandy Heath transmitter.  The red
button logo is alive and well on Freesat today.
