Bt878 based cards would be the preferred ones, unfortunately they are
getting difficult to buy as they have been superseded by the Conexant 2388x
(aka cx88) based cards or some other chips.
It was only recently (kernel 2.6.10) that the V4L compatibility layer of the
cx88 V4L2 driver started to work with vic, with earlier versions, vic would
crash. Currently, the default contrast, brightness, hue and saturation
settings are wrong for the cx88 driver as you end up getting a very dark
picture in vic, to get a descent picture you need to adjust all 4 of the
settings (unfortunately the settings get reset each time the cx88 driver is
reloaded). AGTk has no sliders for the contrast, brightness, hue and
saturation settings, I was thinking of releasing a modified VideoService and
VideoProducer service with these 4 sliders for the next Fedora AGTk RPMs
that I release. I also needed to do a simple modification to the vic source
code to handle the S-video input correctly for the cx88 based Hauppauge
