This is essentially a re-post of the problem here, that hasn't been solved yet:
https://yabb.jriver.com/interact/index.php/topic,115222.msg796562.html#msg796562Since I just installed V. 25 and the problem still exists I'm reposting here in hopes that someone has had a similar problem and found a way to resolve it.
Here's a summary:
I'm just using MC as a media server, and keeping Windows Media Center on Win 8.1 as my primary media center.
Everything works great, I have remote access to all my WMC recorded content, I can stream to JRemote, I have MC's interface working well also, though at the moment I'm not using it. Media server is set to start when Windows starts.
The only issue I'm having is that JRiver Media Server seems to break the skip forward and skip back keys on my Harmony remote acting as a WMC remote (Or the actual WMC remote as well). They stop working in WMC and even MC once the Media Server starts.
My IR receiver is an HP infrared unit plugged in via USB. All other remote buttons seem to work. I did a search and I saw some other complaints about the skip buttons not working, but nothing exactly the same.
If there is a background process called "Media Center XX" running, my skip forward/back buttons don't work in Windows Media Center. If I kill that process they work again. (The main JRiver application is closed).
