Hi all, bit of background before problem.
I was using an old vt card and daughter card with the single vga connector for the sx8. My card recently died and had to return it back to newtek. My awesome dealer New Magic in Australia couriered me a replacement straight away. (excellent service) however they sent a new pro card (i think, different from my old clunker) and daughter card with the two vga connections.
My problem is a I'm doing a 3 camera shoot, all composite, tomorrow and in setup i found I had inputed all cams i could preview all of them, then when you switch back to a camera not on the preview bus (any ,no particular cam) it's gone just black screen only. The only way to get it back is put in on a new input on the sx8. then can switch to it. then when going back to another cam not on preview bus. it then goes black.
So the problem seems to be a bandwidth issue. In my testing i tried inputing all cams into an analogue panasonic mx30 with output going into 1a on sx8. Now if i place the mx30 on colour bars i see the bars no problem on vt switcher preview. If i try to switch to a camera, same issue black screen. If i try a slow fade from mx30 bars to cam, i see the camera at 50% fade then at 100% fade over to cam, again goes black.
Next i tried removing the sx8 and going in with the vga to bnc tails. this works fine from the program out on the mx30.
So can anybody shed some light on this issue. Am i missing something obvious
