Hi all

I'm not sure, but see if any of this helps:
USA help site says: Please ensure that all ad-blocking software is disabled when trying to view full episodes on USANetwork.com. Ad blockers will prevent the episodes from playing properly.
This kinda explains it
: Sometimes the audio or video content embedded in a web page doesn't play in Firefox or Mozilla Suite but it works in another browser like Internet Explorer. This usually happens either because you are missing a plugin or because the web page is coded specifically for Internet Explorer. This Article will help you solve these and other problems with audio and video content on web pages. One member found this out: If you use Firefox, you may have a plugin for FireFox called ad blocker
https://addons.mozilla.org/en-US/firefox/addon/1865 that might be blocking the ad in the video, and thusly preventing you from watching vid. It does not have any problems with HULU with ads. This plug-in ad blocker is more for banner ads on websites. Just disable the plugin and the video will play fine in firefox.
It's also possible that the USA network has been upgrading their video software, and that's why you were able to watch them months ago, but not now. Double check to see if you are able to watch the same BN episodes on
Hulu or
Fancast - That might help determine if it's your browser, or their site. Please note that Hulu & Fancast usually only have the full episodes posted if the USA site has them posted. When the USA takes episodes down, Hulu & Fancast take theirs down.
