We have been using IP control on Directv receivers for some time. My programmer recently set it up combined with XP6 and T2x at my place. The IP Directv control has intermittently been very slow. Push several buttons and nothing happens. Then after 10 seconds all the commands previously sent occur in sequence. It seems they are stored and then catch up. It is not always this way, but pretty regularly occurs. The Roku is set up IP as well without any issues. Any insight on this issue? Tempted to go back to infrared at this point. Thanks
