I'm not sure what you mean by "qvod a". Qvod is a P2P video player software, but I'm not sure what the "a" refers to in your question. Could you please provide more context or clarify your question? Are you asking about:

1. What Qvod is?

2. How to use it?

3. Its features?

4. If it's safe to use?

5. Something else entirely?

If you can give me more information, I'll be happy to help you with a more accurate and useful answer.
