Games dont run from CD, USB memorycard, SD card

Games don't run from CD, SDcard or USB memory
In short: I created a test game for UBUNTU and seems running fine in UBUNTU desktop. But when I try to run it from CD drive ubuntu does not allow running it. I tried all the recommended solutions in documents which should give permission executing files from CD rom, Sd card and others but all failed. Here is the video of the problem please take a look to understand:

You understand if you want to attract quality game programmers to Ubuntu you should allow executing programs from CD rom, USB memory stick and SD card cause external media types allow protecting games from piracy. If not then games published on ubuntu are easy target for hackers. Now that we have wonderful game engines which also allow us to also publish games for Ubuntu you should take this issue serious, otherwise Ubuntu fans will have no other choice but to start making games for other platforms which are now also open to homemade games like android, mac, IOS, xbox and playstation. And the nextgen gameprogrammers will loose interest in making games for Ubuntu.
 I am using Ubuntu 14.04

Thanks for your comments, but why on earth did you post them as a bug against the Ubuntu documentation? You should rather bring up the discussion on some mailing list, e.g.

According to the UBUNTU documentation I have to follow their instructions and things will work out. But it seems It does not work at all as the instrsuctions say. So it's a bug when you follow all instructions and things still dont work as they should.
Here you can see just tried the CD only https://www.youtube.com/watch?v=ydqybNYR6JM&list=UUIR30ZP3s07epFu4mhixumQ
