     Depending on your hardware, the TV-out from an Nvidia card/PVR-250-
based system can be quite acceptable.  While it's not as good as the
350, the Nvidia TV-out looks " good enough" on my system (and I'm using
composite out -- NOT svideo).  You've definitely got to check the
"deinterlace" option, though.

[ I suspect that a good TV-out would also be "good enough" for many/most
  people, although obviously not everyone.  The artifacts/soft images
  seem to occur mainly with fast action/motion scenes, and will (for
  many/most people) probably be unnoticeable otherwise, except for some
  softness (which many people will probably get used to).  I should
  check this, but I'm guessing that the TV-out quality is still better
  than most VCR recordings.  I should also try using svideo, just to see
  if there's any significant difference over composite.  ]
