I am putting a tv on the wall and will have the dvr behind the wall and I don't have one of the big cable companies that has an app to control the dvr. I have looked at IR repeaters which will get the job done, but I will still have to have a device within site of the remote to change channels. Is there a way to convert the IR signal to go over wifi and operate the dvd with an iPhone or iPad via an app? Any other advice on repeaters is appreciated.
