So the TV problem involves the resource pack. Make sure you downloaded the resource pack from the TinLC2 download page and have installed and activated it. If you need help with this, there is a tutorial on the download page explaining how to use resource packs.
I'm not sure why the door did not open, but just break the blocks manually (for the exit on the other side) and walk out in that direction. The redstone should continue triggering, allowing the next player to enter the pod. The broken door will eventually repair itself - just don't leave the pod until the 'selection' is over.
Finally, the latest version is map version 1.1.
You should be playing the game in Minecraft 1.8, as sounds etc. will not run on future versions of minecraft.
Hope this helps! Feel free to write back if you are still having issues.
