In the FAQ this link are dead :

@section Why does the chrominance data seem to be sampled at a different 
time from the luminance data on bt8x8 captures on Linux?

This is a well-known bug in the bt8x8 driver. For 2.4.26 there is a patch at
(@url{http://mplayerhq.hu/~michael/bttv-420-2.4.26.patch}). This may also
apply cleanly to other 2.4-series kernels.

@section How do I avoid the ugly aliasing artifacts in bt8x8 captures on 
Linux?

Pass 'combfilter=1 lumafilter=1' to the bttv driver. Note though that 
'combfilter=1'
will cause somewhat too strong filtering. A fix is to apply 
(@url{http://mplayerhq.hu/~michael/bttv-comb-2.4.26.patch})
or (@url{http://mplayerhq.hu/~michael/bttv-comb-2.6.6.patch})
and pass 'combfilter=2'.

I search for others links to these patch and all references are on 
ffmpeg mailing list
must have to remove this link  if the new linux kernel versions are OK ?

A patch :

 Nowhere. Upgrade to the latest release or if there is no recent release 
upgrade
