        1. The attachments are probably being filtered by a content rule or even a browser policy.

        2. YouTube serves videos using Flash or HTML5 from a number of content servers. To block only the videos while leaving the main site accessible, you would have to identify and block every content server, and even that would only work until YouTube decided to introduce new servers. Have you considered using a DNS or URL filter?

        3. Skype is a bloody chameleon and is quite good at tunneling through most firewalls. If general HTTP or HTTPS traffic is allowed, Skype will get through. It can be blocked if the firewall has the right filtering options (a Google search turned up some ActiveWall and SonicWall examples), and as it happens, TMG has a filter group called "chat" that supposedly includes Skype, but reports suggest that it's less than 100% effective.

        TMG 2010 is unsupported, and the entire TMG product line has been discontinued by Microsoft. You should seriously consider replacing TMG in the near future.
