I have a Phillips MCE remote that came with my Zalman HD-160 case. When I press up or down on any menu in Media Portal it moves up or down 2 entries, instead of going to the next entry. For example on the main menu, if the entries are listed in the order My TV, My Music, My Videos; if I'm on My TV and push down, it skips My Music and goes to My Videos. I also set up my Harmony 880 remote for the Zalman case and it does the same thing. Any ideas?
