I had a bit of extra time this weekend, so I answered my own question. Here's the mpls list for Grantchester series 4 if anyone's interested:

Disk 1
episode 1: 266
episode 2: 802
episode 3: 777

Disk 2
episode 4: 409
episode 5: 268
episode 6: 750

Has anyone figured out the obfuscation for Grantchester series 4 yet?

Thanks!
