Beocenter 2 DVD-OSD

Dear all BC2, DVD version, connected to a BV3-32. Are next to each other, both in Opt. 1. DVD plays allright, but three things are annoying. Go button at Beo4 sometimes doesn't seem to work. And I can't get DVD OSD to be displayed. When I quit watching DVD and switch off, the TV stops but the DVD continues. What is it? Setting at BV3, BC2 or Beo4? Or Beo4 config (DVD / SAT version)? Please help. THX !
