Hi Everyone,
i'm experiencing a minor issue when capturing streams from the composite
input. Overall I get good sound and pictures quality is ok although I can
notice a white vertical line scanning from left to right on my tv and I was
wondering if there was anything I could do to fix that. I tried the
different PAL standards without success.
I've checked the source by plugging the composite cable directly in the TV
and it's fine. I've also played the mpg files on another PC and the problem
is still there so it's not a playback issue.
Any help appreciated,
Thanks.
