RemotingMessage vs. RemoteObject in AS3 help needed

Question

Hi,
Could someone clarify the difference between using RemotingMessage and RemotObject to invoke RPC in AS3 code? I found two different examples online and I don't know, which one is preferable.
--first example http://www.ghost23.de/blogarchive/2008/10/connecting-flas.html --
var remotingMsg:RemotingMessage = new RemotingMessage();
remotingMsg.operation = "multiply";
remotingMsg.body = methodArguments;
remotingMsg.destination = "calculate";
remotingMsg.headers = {DSEndpoint: "java-amf"};
var respnd:Responder = new Responder(onResult, onFault);
netConnection.call(null, respnd, remotingMsg);
--end of first example--
--second example http://www.flasher.ru/forum/blog.php?b=44 --
amfChannel= new AMFChannel("my-amf", "http://192.168.10.38:8080/samples/messagebroker/amf");
amfChannel.requestTimeout = 3;
amfChannel.connectTimeout = 3;
channelSet = new ChannelSet();
channelSet.addChannel( amfChannel );
amfChannel.addEventListener(ChannelFaultEvent.FAULT, handleChannelFault);
amfChannel.addEventListener(ChannelEvent.CONNECT, handleChannelConnect);
amfChannel.addEventListener(ChannelEvent.DISCONNECT, handleChannelDisconnect);              
ro = new RemoteObject();
ro.destination = "hello";
ro.channelSet = channelSet;
ro.addEventListener(ResultEvent.RESULT, onResult);
ro.addEventListener(FaultEvent.FAULT, onFault);
ro.getOperation("hello").send("Piter2");
--end of second example--
The first one is shorter but it is not clear to me what are the implications of choosing one way over another.
Thanks

If you have a button on the same timeline as your code with
the instance name of abt_mgn_btn, then, when this button is
released, the playback head will jump to frame 10 of the current
timeline and continue to play.
If you want the playback head to jump to that frame and stop
then, either use gotoAndStop(10), or put a stop(); command at frame
10. GotoAndStop() will work more reliably.
