We upgraded all our CE-507's & CE-560's with ACNS 4.x to CE-510's & CE-565's with ACNS 5.x. Since then a few of our videos started to buffer before playing. Depending on the size of the video, it can now take several minutes before the clip will start playing.
In 4.x, we didn't have WMT enabled, not license keys installed, and the problem videos would play correctly. So I'm really stuck as to what is causing this.
Any help is appreciated
