Same here. And even when using a WinTV card with 'fxtv'
(http://people.freebsd.org/~rhh/fxtv/) on a BSD system I was using
mjpegtools to perform the processing of the data. After seeing the
difference between what a Bt878 and a Canopus ADVC100 (although today
I'd get the ADVC300) produce I pulled the WinTV card out and put it
in a static bag ;)

Exactly. The code for capturing in mjpegtools is a relatively small
portion of the total - the bulk of the code resides in the (wide)
variety of filters (couple denoisers, medianfilter, stabilizer, and
so on), scaling, and especially the encoding and multiplexing (mplex
is often regarded as the "standard" against which others are compared).
