Those who are paying attention and have a sharp eye may have seen a reference to an easter egg in the screenshots for the pro version.
There is in fact an easter egg in the PRO version that has been there since day one. I put it in there one night as a joke when getting the app ready for its initial release.
At this point I am not going to give too much away about it. However, starting with DirecTV Remote Pro v2.2.2 and higher, stumbling on the easter egg will get you a "code" that you can email me and I will give you a link to a very basic DirecTV Remote for Windows that I made when testing DirecTV's network / IP control when it was in beta.
It does not do automatic discovery (scanning), favorite channels or macros, but none-the-less you can control your receivers from your Windows desktop or notebook using it. Hey, it's free! What do you want?
