RadMediaPlayer JavaScript error.

I get the following error when attempting to start (by cliking on the media player) a video. Can anyone help me to resolve this?

Unhandled exception at line 2779, column 33 in http://localhost:59591/Telerik.Web.UI.WebResource.axd?_TSM_HiddenField_=RadScriptManager1_TSM&compress=1&_TSM_CombinedScripts_=;;System.Web.Extensions,+Version=4.0.0.0,+Culture=neutral,+PublicKeyToken=31bf3856ad364e35:en-US:fa6755fd-da1a-49d3-9eb4-1e473e780ecd:ea597d4b:b25378d2;Telerik.Web.UI:en-US:ad3df475-29ac-40bb-8405-97ab474c3782:16e4e7cd:f7645509:22a6274a:ed16cbdc:24ee1bba:c128760b:6ec8ee1b:874f8ea2:88144a7a:1e771326:f9b9258:fd9da3ae

0x800a01b6 - JavaScript runtime error: Object doesn't support property or method 'PlayMedia'

Hi Dean,

Can you please remove RadCompression from the web.config of your application and let me know about the result?

Hi Dean,

The most probable reason for this issue is that please make sure all required Javascript files are registered on the page and there is only one jQuery instance.

Thanks
Shinu
