You might have seen the other thread where I've determined that Linux and BusyBox are running on the remote. These pieces of software are licensed under the GPL and as such you as an owner of a remote are entitled to an offer to get the source (by mail order, download, or whatever).

Have you seen any mention of the GPL in the documentation or an offer to order or download the GPL software that is running on the remote? Is there a CD distributed with the remote that includes the source code?
