The error:

I get the following error:
We encountered an error while trying to access your Sitemap. Please ensure your Sitemap follows our guidelines and can be accessed at the location you provided and then resubmit.
1
URL restricted by robots.txt

given by Google is correct, and i'ts due to the sitemap link itself that is blocked in the robots.txt:
Disallow: /index.php

About the fragments: /video/player/ they are good for SEo so you can make that open for indexing.
I suppose they are generated by the extension HD video share, in this case i can go on to help you to find correct integration with JSitemap.
