You should have a menu structure that looks something like this in your 
TV settings:

Recording Profiles ->
    MPEG-2 Encoders
        Default
        Live TV
        High Quality
        Low Quality      
            
    Transcoders
        RTJpeg/MPEG4
        MPEG2


If you navigate to the MPEG2 section of the Transcoder profiles, on the 
third page is the setting for your codec, you should be able to chose 
MPEG-4 there.

Are you sure it wasn't 1.2G?  That sounds about right 3k.   You didn't 
mention what your max bit rate though. You should have two.

When it transcode it uses the MPEG2 transcode profile.
