I don't use a dazzle and have to use some "different" stuff to capture.  
So I'm not too sure. 

Two thoughts:

(1)  Check to see if /dev/video0 (or 1 or 2) exists.  To do this, unplug 
the grabber and :
$ ls /dev/video*  there will be a file for each existing and working 
video device.  Then replug the grabber and do it again.  Then new 
listing will be the grabber.

If you don't have a something that looks like this:
crw-rw----+ 1 root video 81, 0 2009-09-20 15:29 /dev/video0

then go to the next brilliant idea.  But if you do have something, 
ffmpeg or mencoder can grab the stream.  The man page for ffmpeg says this:

"
 Video and Audio grabbing

       FFmpeg can grab video and audio from devices given that you 
specify the input format
       and device.

               ffmpeg -f audio_device -i /dev/dsp -f video4linux2 -i 
/dev/video0 /tmp/out.mpg

       Note that you must activate the right video source and channel 
before launching FFmpeg
       with any TV viewer such as xawtv (<http://bytesex.org/xawtv/>) by 
Gerd Knorr. You also
       have to set the audio recording levels correctly with a standard 
mixer.

"

(B)  Google: linux dazzle dvc-800 grabber.  Probably lots of folks have 
written up this device or something in the dazzle family, they are very 
common.
