The question first: Maybe I'm missing it but I have not been able to find instructions on a simple way to fast forward thru the commercials. I primarily use the Apple TV controller app on my iPhone which is infinitely better than the awful remote that comes with it. I would be willing to purchase an inexpensive controller if that were the only way to accomplish this.
Now the comment: I have been absolutely amazed at how simple this whole thing has been to set up. I already had my iMac and Apple TV connected to my network by ethernet and had tons of storage available on my iMac. I bought an antenna and the Homerun Quattro refurbished from Silicon Dust directly ( same price as a new Duo ) and plugged it into the ethernet connector by myTV, subscribed to Channels DVR and everything just worked. Could not believe it. I am discontinuing my Direct TV this week and might subscribe to Sling. Couldn't be happier!
