Not perfect, but...

The good folks at YouTubeTV wrote me and said that AppleTV app was due “soon” so that is worth 3 stars right there.
This app has allowed us to finally cut the cable and stream everything we want to watch as well as use the fantastic DVR capability. Our TiVo is only thought of fondly when the app acts up otherwise we don’t miss it at all.
