Well, in v4l2-apps/test/capture_example.c we see:

	if (req.count < 2) {
		fprintf (stderr, "Insufficient buffer memory on %s\n",
			 dev_name);
		exit (EXIT_FAILURE);
	}

so, they seem to refuse to run with fewer than 2 buffers. But if I remove 
this restriction and enforce 1 buffer, it works. 2.5 times slower, but 
works. Can there be a problem with your application? What kernel sources 
are you using? Try using the latest v4l-dvb/devel git.

Thanks
