mr_anders_son: I have a BV7-32 in bedroom. Is it in some way possible to use the internal DVD to watch in my mainroom on my BV9?
Should be possible via Av1 port on your 7-32 as long you don't want to control it from the main room.
The Scart plug must have an output (composite,RGB?) for video recording. Connect this output with a Scart input of your BV9.
I never tried this constellation, but as far as I know, all Beovisions have an output on Scart AV1. Selected Picture and sound are automatically routed to this port. You don't need HD signal, DVD player is SD.
