you should either
- capture from DVB (digital TV/sat), they broadcast in ~6mbit/s mpeg2
- capture from analog TV/sat but using some noise removal filters at
  capturing time, then lossless compression will go better.

for example -vop pp=dn:c:64:128:256 is a good start, but we definitly need
a better, pre-pixel noise filter, with motion compensation etc.

you shouldn't capture at 640x480...
and for any Y res >288 you should do deinterlacing too.
