On page 58, you can find the GPL license and this is a snip form it:
Your Rights Under the GNU GPL The software used in the Home Media Centre is based on GNU General Public License (GNU GPL) software, with some further enhancements and modifications. This gives you, the purchaser, certain legal rights including the right to examine, modify and re-distribute the source code without the permission of Development One. To allow you to do these things, Development One has placed a copy of the Home Media Centre source code on the unit itself. In order to access the source code you will need to connect a VGA monitor, keyboard and mouse to the appropriate ports on the back of the unit. You can then logon as user ârootâ with the password âHomeMediaCentreâ. You can find the source code in various directories under â/root/hmc/â. For further information regarding the software and the modifications you may make to it, refer to the MythTV PVR Project at http://www.mythtv.org. However, be aware that you may only modify and distribute the source code in accordance with the GNU GPL. Before you do any of these things please ensure you fully understand your obligations by viewing the full text of the GNU GPL at http://www.gnu.org/licenses/gpl.txt. So the software is not violating of the GPL in anyway ...... If someone ownes a HMC, he can do a diff with the mythtv source and see what they changed. Maybe some changes can be contributed back to the mythtv project. Or he can compile his own binary's and resell the HMC, there is nothing they can do about it. Stef
