Is it right that the space player has to give the CDs to all the players pre-SBURB? If no, could the beta-kids start without a space player and the time player would just scratch and maybe one of the alpha-kids is a space player? (Sorry formyenglish)

No to both questions. Jade didn’t give anyone discs in fact she was the last to get them and they were the pair Dave lost. And Kanaya wasn’t involved in the game distribution at all.
