Just have a myhtpc config with everything removed except the TV module. How do you do remote control.? This is probably the harder bit. You will have to have an Xlobby event that causes the running myhtpc screen to come to the front probably via girder. This of course where it gets messy.
Wow, thanks for the large response. My XLobby pc is being reinstalled at this moment, when it's ready I will try to get the TV working. (maybe ''ll have some more questions)
