Since this is in nostupidquesrions and a piracy community I’ll offer a different take:

Try your local library for physical copies. Depending on your library system, it may be free (or low cost) to have copies sent from other branches. Again depending on your system it may be possible to get copies from libraries outside of the system through Inter Library Loans (ILL) if your library participates.

Also library systems may have access to some streaming content, depends on your system. Some large cities, like NYC, offer library cards to everyone in t the state.

Tangentially related, the Internet Archive also hosts tons of material you might not find anywhere else. Probably not what you’re looking for, but I’ve found things like Mister Rogers episodes there that aren’t available on Amazon or DVDs. Quality of content may vary and you’re more likely to find older content there.
