This is worrying - the patch adds code to handle these 2 cases which are
essential to 'Interaction Channel'.

> SetSubtitleMode ResidentProgram is not implemented

This also should be handled by the patch, but isn't essential to
operation.

It looks like the patch didn't apply correctly.  The patch should be
applied to current, clean git fixes/0.24.  Also, make sure that you have
the latest patch, last updated on 6th September, which is applicable to
today's git fixes/0.24 (v0.24.1-85-ge16613a).

Try this:
# skip this if you already have a good/clean 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

The patch should apply cleanly with no errors or warnings.  If the patch
still fails then your repo may be corrupt.

Then run ./configure, make and make install as normal.

If you want to try with git master (v0.25pre-3366-g1e2c9da) then use
this patch:
http://www.softsystem.co.uk/download/mythtv/iplayer-master.diff

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:
MYTHMHEG=noice

To use an http proxy set: MYTHMHEG_PROXY="http://192.168.0.1:8080"
or MYTHMHEG_PROXY="cache://192.168.0.1:8080" # for an http caching proxy
or MYTHMHEG_PROXY="socks://127.0.0.1" # for a socks proxy
