I've been using Jump Desktop to connect to my HTPC on both my normal Windows desktop and my Android device. I mainly use it to schedule programs I forgot to add (e.g. football games), so I don't connect that often. The HTPC is running Win7, and the normal Windows desktop used to connect is running Win8.
Now I can connect, but I can't get WMC to run via the connection. When connected through my desktop I just get the message right away that WMC stopped working. When connecting through Android I get a message that the color resolution isn't high enough.
I've made two changes recently.
First, I installed Win8 on the desktop on which I connect through. I did that the first day Win8 was available, and I don't remember whether I've connected since then or not.
Second, I've changed displays on the HTPC to a 1080p display (before it was 1080i).
Since it won't start WMC using either Win8 or Android, I assume it's not related to Win8 being added to the normal desktop used to connect.
