This bitrate seems a bit excessive to get a good picture - I've used
similar settings to Nick Rosier 4000/5500 and get perfectly fine video
(PVR-350 using old ivtv version 0.2.0-rc3f!).

These lines still sound like interlacing artefacts - you don't need
much motion to be able to spot them - a non-static picture is all that
is needed if you do not have deinterlacing enabled.
