This is normal -- simplegrab does a number of test scenarios and the
one that is failing is the "double default test". This test tries to
acquire a default source twice. Since you only have one video device
attached to your system, it makes sense that the second attempt to
acquire a source would fail.

You can choose which tests simplegrab runs. Try "simplegrab -h" to see
its options.

You are welcome. I appreciate the positive feedback. Good luck!
