Hi all,
I have 2 LeadTek WinFast TV2000 XP Expert analog capture cards. I'm
attempting to get 4 channels of video in, using both the S-video and
component inputs (not the tuners) of each cards. I understand that
this was possible with the bt878 which this chip is an evolution of.
However, it doesn't work.
1 channel on each card gives no signal on the "second" card- i.e. the
one initialised second. This is from tests with and ZoneAlarm (the
application I'm trying to use the cards with).
2 channels on one card kinda works, but not correctly. Sometimes one
channel will display vertical split-screen of both feeds, with a
little noise at the top, bottom, and in between. Sometimes each
channel will display correctly, but will appear to "vibrate" up and
down, and the channels seem to alternate between which one updates. I
can provide screenshots of both these behaviours if it will help.
I've tried this with the following kernels:
2.6.29-larch
2.6.17-10mdv
If someone can point me in the right direction I may be able to do any
patches required myself, but I need a starting point.
Thanks in advance,
Adam Swift
