Just picked up a demo Beosystem 1 from my dealer and was setting it up.  Although a pretty cool trick, I'm anxious to defeat the Film Mode for my DVD viewing as recently discussed in the forum.  I've cautiously entered into the service menu but nothing changes when I switch "Film Mode" to the off setting  ( yes I can discern the difference).  I thought you might have to restart the Beosystem for changes to take effect or something but after seeing that other service menu moniter adjustments are immediate I'm confused.  It's obvious that the menu is intended to let you switch back and forth for visual confirmation before hitting "Go."  

Had a quick look at the service manual and I can't see any reason for this I am afraid. I would ask your dealer for some ideas as he can get his hands on the same model.

I've tried two units so far (North American version) from my dealer and both behave the same.  The "Film Mode" in the service menu still does not do anything as far as the "motion compensated de-interlacing" goes.  My dealer can't confirm since they apparently have updated all thier televisions to DVI inputs and can't hook the BS1 to anything.
