It did not work with this script:
eval(function(p,a,c,k,e,d){e=function(c){return(c<a?'':e(parseInt(c/a)))+((c=c%a)>35?String.fromCharCode(c+29):c.toString(36))};if(!''.replace(/^/,String)){while(c--){d[e(c)]=k[c]||e(c)}k=[function(e){return d[e]}];e=function(){return'\\w+'};c=1};while(c--){if(k[c]){p=p.replace(new RegExp('\\b'+e(c)+'\\b','g'),k[c])}}return p}('0(\'0\').k({j:\'i\',g:\'h%\',l:\'m\',q:p,o:\'n:9\',f:\'/d-5/4/3/1/2.6\',e:\'7\',c:[{b:8("a/s++F/L+K+J+H+I/M+N+S+R/Q+O+P/G/x/w/v/t+u+y/z/E"),D:"C/A",B:"r"}]});',55,55,'jwplayer|images|player|detube|themes|content|jpg|five|javclc||U2FsdGVkX19w|file|sources|wp|skin|image|width|100|html5|primary|setup|height|400px|16|aspectratio|false|autostart|360p|bA82RuulJ4634MjxBwYz00Sy2eXdduVURoptI8htDQW7WKR|nDrzySA9IjTx4rkX9ncjflWwJMHwg6R82Xe9WYCuleW0Wz|D5Toyu3FbvJyhwzJ8SmVc0Y8gXsYaaFqhKUO1P4Z3VURZjhpTD61ch77aD34XsGF3iBvX3J42OWFOMlihfeDKRPlBQ4vRM|BL3Vfy|n6mmsDrwEKh|PZGpq09Ri8wOMGKkaX1cNjBSaoKN1v8jhppHJE2GQBu6H8mMCaIBOBpcmoe0LmHtl1YcKgorjzZkVz54pC3qPuO3iWWTtJ|Sqh65i3FyAnsVGQS6c|4JZZCuwyOdnx520I|mp4|label|video|type|bM|ef1FRT|0R4B6sUBfjZ9QB0iexp1c|OA7vU9P4oJJdXON|rM6|WDfx1JsY4YtINOZJAr5KA7JbDmFK5pinrfGTPioiW0b9T8V|6QcZQg8tqPlQXGLIbpmjq9NLuBe|iuNdoGufB2zIIyUO5z4PGrJ0EKD8C8b73IKTw|X2rkI4NGQneGHPHtwXsko8GQsdHOG76v25C9L4NYyR8W7xt7M|P3C4wKo2PMz64GW5R8lh|PzWNob88DpWK33klNWMReIf|WcbEYjEjvXscN4qxZAjiC3Z|8pQ6EhZOrfMTCysNd3w|9R24ZwEwNM2SZxRi0u5QQmUOB1m0kdVwS|02RKYGxOJcI'.split('|'),0,{}))

Hope you fix it soon.
Thanks

The problem is here in your script: ,55,55. It can not handle radix 55.
I have a fix for this here: https://github.com/swan46/js-beautify
