This is on Youtube TV. My internet speed is 15 megs and the only buffering is for the first 5 seconds or so. Granted, we usually aren't streaming more than two at a time now that we have a couple of our oldest out of the house, but I can't remember the last time that we had buffering issues.

DVR works identical to my old Directv setup other than the skip forward and back is 15 seconds at a time instead of 30 and 10. That literally is the only thing I have noticed that is different about the DVR, except for the fact that it's unlimited.

I love youtube tv. No contract, so I can cancel or pause anytime. If I pause for less than a year I can keep everything in my library (their word for DVR) and still have it available when I start back up.

So much less hassle than dealing with Directv for any kind of customer service type of things.
