TiVo records the earliest possible showing if it has a tuner free. So go into Manage My Series Links and move Matrioshki to the bottom of the list. This will make it the lowest priority recording, so anything clashing will take precedence. Also to reduce the chances of clash messages, go into recording settings, and change Overlap Protection to "cancel lower priority show".

(But if you really do want to force it to record the later showing regardless, you can do this with a Manual Recording)
