Well, now that our main Tivo Series 4 is dying. We are trying one last step, but now using the Comcast DVR alot and Plex from the Mac Mini. Seems like this doesn’t work super well as this requires KMTTG to download from yet another Tivo.
To get rid of this dependency time to try MythTV again. Good news is that in the last few months, someone has now moved to Macports so that instead of burying all the perl and other files into a Applicaiton package it is exposed and the various addons can work. Ideally, you should be able to see live TV, recorded TV and moives and things from a server all from one front end without needing a Tivo
Of course you do need to install lots more scaffolding in particular, xcode, xcode command line tools, and macports.
