Adobe Media Server DVR only 5 second recording

I have a strange problem. I have an application built in Flash Builder.

When I record to Flash Media Server I don't have any issues, it'll do DVR for as long as I want. But when I record to Adobe Media Server, the recording is only 5 seconds long.

ns = new NetStream(nc);
ns.client = new Object();
userUID = UIDUtil.createUID();
ns.attachAudio (mic);
ns.attachCamera (camera);
ns.publish( "demo" + userUID, "record" );

Later I can play the recording, timestamp says that it's a 5 second archive, but it'll really keep playing the recorded video.

Same code, just different server.

Has anyone had this problem when migrating to Adobe Media Server from Flash Media Server? Using Amazon.
