this is a common problem. you'll need
discrete codes to make this work.
what dc's do is allow you to send a *specific* signal to the component. common ones include power on and power off. you'll have to be sure your component supports dc's too - i think most sony's do.
i'm not sure about your specific remote, but i have the hometheatermaster mx-500. for discrete codes to work on this one, i first have to program them into
another remote first. then i send that signal to my mx-500.
hope that make some sense..if not let me know.
also, be sure to check out the forums at remotecentral.com - they have one specifically for sony remotes.
