For those having issues with uStream and possibly other services not playing in IE8 but working with all other browsers you can try the following. Going in to media_service and changing the svcMovie row from
Code:
http://www.ustream.tv/flash/video/{serviceVAL}?autoplay={apTF}
to
Code:
http://www.ustream.tv/flash/video/{serviceVAL}
For whatever reason Internet Explorer isn't playing nice with any "?*=" and simply removing them seems to fix the issue. At least I know it's working for uStream. It might for other services as well. Hope this works for anyone else who is having an issue with this. I know that doing this videos still play just fine on Firefox, Internet Explorer 8, and Safari. I haven't tested to make sure Chrome still functions fine by removing part of that code but I assume it does.
