Copy shows from Roamio to Mac

Hello,

My cable box is a TiVo Roamio (I think) leased to me by my cable company, Atlantic Broadband in Miami Beach. I have the TiVo iOS app to download shows to my iPad and iPhone, but I'm curious: is there a way to download shows to my Mac? Would be nice for my wife to be able to use her MacBook to watch shows when we travel, instead of sharing my iPad or using her iPhone.

I came across a couple of apps on the web like cTiVo and Kmttg, but those are 3rd party solutions. Are those the only ones available, or does TiVo provide a first-party solution I'm unaware of?

Thanks in advance for any help you can provide.
