I wasn't sure to post this in the Harmony forum or the HTPC one, so I figure I'll post it in each and see what happens. My problem is as follows:

I have a new HTPC with the LG Combo Blu-Ray/HD drive and have to use PowerDVD Ultra to play the new format discs. My Harmony remote controls the media center experience perfectly, as I expected it to. However, when PowerDVD launches to play the HD and BR movies, I can no longer use the remote to control playback. If I try to skip chapters or hit the menu button, it brings Media Center back to the front and leaves the movie playing in the background. Using the remote (I'm keeping it as simple as possible for my family), I can't switch back to the movie. In the Harmony software, the Chapter Next and Previous buttons are actually mapped to Skip and Replay, which Media Center interprets correctly but which mess up my HD and BR experience.

So, my question is this. What do I need to do in order to make my Harmony work with PowerDVD?
