Hi, I've read the other threads about this, but I'm still having trouble. I went through the included instructions and set up the Harmony software using the Schmartz and PS3IR-PRO, and that worked out ok. However, I'm stuck when registering the remote as the BD Remote on the PS3. Once the screen says to "press x and start simultaneously," I then plug in the PS3IR-PRO to my Uverse cable box (tried my Samsung tv, too) and then pointed the remote at the infared receiver and held 0 for about 25 seconds. I've tried this multiple times, but it never pairs up and just stays on that screen. Any help would be greatly appreciated. Thanks!
