Hi All,

tl/dr: 
My Beocenter 1 image is nice and sharp, but has an image stability issue, shake/wobble particularly at the outer edge.  It looks like an auto focus trying to activate continuously.
I only use it for 90s video games consoles, so 50/60hz RGB input.  60hz is slightly worse, but this is probably due to the larger picture.
I also own an older MX4000, which again has a fantastic RGB picture, maybe a little duller than the BC1, but a solid steady image.  My thinking is there must be a way of matching it with the BC1 in terms of quality.
...The longer version...
So as above, the picture is great I just wish I could get a stable image.  
I've looked online (inc Beoworld) and the issue does appear to have cropped up before, some points I've found:
...Please also note I'm a technical novice, so some of this might not be relevant at all...
De Interlace Function

This you tube video is interesting (hope it's okay to link) 
So he uses the beo4 remote to switch to de/non interlace mode to get scan lines while using an xbox 360 on his MX model CRT.  
At 3:50 in the video he highlights a similar wobble/shake to the one on my BC1.
So my thinking is that the newer BC1 has this non interlace as a permanent input feature perhaps?  So it's more relevant to games consoles and devices of that era, PS2, xb360 etc?
Sync / Pin 16
Is there the potential to hack a scart to scart cable (I use a switch box so all consoles go through one cable) with a potential fix using a resistor or cap etc to help with older 240p input signals?
If anyone has any ideas it would be great to hear from you! ...many thanks for reading.
:)
