That's because the tuner needs to scale.  You'll have artifacts.  If you
could use 360x288 I think you'd find the artifacts would disappear and the
compression would drop.  I'm not sure if you can use geometries that aren't
in the list though...

Welcome to the wonderful world of MPEG-2!  That's really not bad when you
think about it.  A 300g drive (which is cheap nowadays) could hold 77 hours
of full DVD-quality video.  If you're anticipating permanent storage you
may wish to look at ffmpeg, mencoder, transcode, etc. and reprocess the
video after it's saved.  I'm actually happy that it's about 1MB/s without
artifacts!
