If you have a Samsung NTSC or PAL tuner (TCPN2221P30A or TCPG62221P30A)
then please test the attached patch (against ivtv-0.4.5). It turns on
the Low Noise Amplifier of these tuners which should result in a better
picture.
What I would like to know if this patch causes any adverse effects: e.g.
channels that were good originally are now degraded instead of
improved.
Thanks,
Hans
