Hi:
I copy those code from local demo on my empty and practice site.
<telerik:RadMediaPlayer RenderMode="Lightweight" ID="RadMediaPlayer1" runat="server" AutoPlay="true"
Height="360px" Width="640px">
<PlaylistSettings YouTubePlaylist="PLvmaC-XMqeBb991YNEWAHYL9ZJAeURr-r" Mode="Buttons" ButtonsTrigger="MouseDown" />
</telerik:RadMediaPlayer>
but when I run, only media player and other nothig.
The same code on local demo can run very well, What's happen on my site ?
