When I run the homegroup troubleshooter, I get the error message "Homegroup permissions are incorrect - not fixed". I can see other win7 computers in my homegroup, but not my wdtvlive. I've been unable to find out what permissions need fixing. Can anyone help?

You may temporary disable or uninstall the antivirus and check the result. Regarding HomeGroup permissions, I suggest you check the permissions for each shared folders. Make sure that the use HOMEGROUP and NETWORK SERVICE are allowed to access the folders. The wdtvlive may be not related to HOMEGROUP. I suspect that it is not compatible with Windows 7.Please remember to click Mark as Answer on the post that helps you, and to click Unmark as Answer if a marked post does not actually answer your question.
