Hi all, thanks for the response.
Actually, it is a straight NTSC video input and there aren't channel
selections.
In fact there isn't even a tuner on the card (straight BTTV capture).
Apparently, other settings on the device itself are occurring which either
I missed
in my transcode parm settings, or is not taken care of when transcode opens
and initializes
the device. Maybe you all understood it this way, and you are saying that
'proper'
channel freq selection *is* the problem?
for convenience & reference, here's the command syntax below.
-thanks,
