Note: I realize it's a preview release.
Flash 10.1 seems to break JW Player on my site (using RTMP streaming with SimpleCDN). I get an endless spinner whereas older versions of Flash work fine, as do other players such as YouTube, Vimeo and Flowplayer. This happens on both my Mac and Windows PC after updating.
Just want to see if this is known to the devs. Thanks.
Same here -- with Highwinds CDN.
