I spent the night with my BS3 until 3 in the morning....
with some new findings:
I tried the 60Hz options with sucess, so I can watch TV now...however, with 60Hz you see judder watching PAL TV (very obvious with news channels with a ticker running). So 50Hz is a must.
My Toslink to SPDIF converter (from my local B&O store) does not work with the BS3, I need to check if it works with my BV3-32😝
Also some settings have no effecht, like audio via HDMI, if you select SDIF instead of HDMI it is ignored and HDMI audio is still active
Also the picture prozesser of the BS3 makes the image much darker. (I compared the direct connections of the HD-DVD player to th projector and through the BS3). I changed the Brightness on the projector to get a better image. However, in the BS3 service menu are sooooo many settings to adjust the image and also I don't know the effect of the missing display identification to the auto contrast or black lever adjustment.
I hope I can get the dealers BS3 today for a cross check.
