Increase max recording time past 600?

So when I try to increase max recording time for video or audio past 600 seconds I get an error from boonex "Maximum recording time should be less than 600 seconds". 

How can I increase that number? I want to allow a 900 second limit on audio recordings and 1200 on video. Any suggestions? 

You need to edit flash/modules/video/xml/settings.xml file, the following code:

<item type="number" key="recordTime" default="60" range="10:600"><caption><![CDATA[Maximum recording time (secs)]]></caption></item>

TY! 

If anyone else is looking to modify audio and video record time length you also need to modify the same variable in  flash/modules/mp3/xml/settings.xml :)
