I got it to work for me (thanks Mark) using 0.6.2 and 2.6.16.19

These need to be changed in both the cardinput and the capturecard
tables. Some SQL like:

  UPDATE capturecard SET defaultinput = 'S-Video 0' where defaultinput =
'S-Video 1';
  UPDATE cardinput SET inputname = 'S-Video 1' where inputname =
'S-Video 0';

(assuming you only have one S-Video card)

This is due to early ivtv drivers numbering cards from 0 upwards whilst
the latest driver numbers the cards from 1 upwards as it  adopts the v4l
standard in order to be included in the kernel.

However I did find I had a very interlaced picture so I reverted to
tried and trusted 2.6.12 and 0.2.0-rc3k.
