You can claim Category C PDUs for all episodes that you listen to. This is explained by PMI in the "PDU Category and Structure" document at https://pmi.org.in/PMPRenewalGuidelines/downloads/pdu.policy.pdf under Category C:
Qualifying activities must be relevant to project management, project risk, project scheduling, or program management, meet a specified purpose, and use knowledgeable resources.
In other words: As long as the training is about project management and from a knowledgeable resource PDUs can be claimed.
