this sample is very dark and in a 2.35 AR => hight compressibility.
it as also a lots a block in some aeras.

i've tested and used a lot mpeg1 and mpeg2, with hdtv here's MY visual impression:
hdtv mpeg2 > 10 mbps looks good.
hdtv mpeg1 > 15 mbps looks good also.
hdtv mpeg2 < 6 mbps looks like crap.
hdtv mpeg1 < 9 mbps looks like crap.

with a very good mpeg1 encoder with custom matrix, and 3 or more passes, i think it can do good looking HDTV quality around 9-10mbps, less than that is a dream.

ps: i have better result in encoding mpeg1 with quenc than with tmpgenc (and it's free).
ps2: if it's for hdtv archiving on DVD media, just use mpeg2, you will always have a better quality, and all graphics card (since around 1999-2000) have full mpeg2 hardware decoding
