I am a Plexpass member, but I think I just have the regular version installed. But nowhere do I see a spot to enter a MAK. I found an XML file that I tried changing the MAK on, but that didn't work either. From what I have read, I should be able to see my TiVo, regardless of whether or not I have a MAK. The MAK is just required to download and decrypt the TiVo files. This is what mine looks like. I don't think it looks right, but I can't find screenshots elsewhere.
