You don't have a /dev/video0 device.

Vertical Blanking Interval. During the VBI, the TV isn't drawing to the
screen, so broadcasters use the VBI to transmit additional (non-visual)
information, i.e. Closed Captions (CC), Wide Screen Signalling (WSS),
Video Programming Signal (VPS), and/or Program Delivery Control (PDC).

The problem could be any of the following:
a) Your system has defined the video/vbi nodes underneath some
directory in /dev, such as "/dev/v4l." If this is the case, you should
be able to find it with a simple:
find /dev -name 'video*' -print
b) Your system does not have any devices defined for video/vbi and you
are not using devfs or udev. If that's the case, create the appropriate
nodes as described at
http://mythtv.info/moin.cgi/IvTv_2fPreRelease10Docs_2finstall (note that
the same commands can be used even if you're not using IvyTV).
c) Your system is using devfs or udev, but for some reason is not
creating the video/vbi nodes. More likely, though, if using devfs or
udev, the nodes are being created under some directory, and you haven't
found them (i.e. as described in a).
d) Something I haven't thought of. :)
