Alfatron 24P F3 SDI-A problem
 

I posted this on DFVX User and didn't get much response so I'm checking here to see if anyone can confirm my experience.
I tested a friends Alphatron on an F3 and I like the picture a great deal when in 30P. However a1080 23.98P it looks great out of the SDI monitor out, but terrible out of the SDI A . Like 1/2 resolution or something. Settings don't seem to matter whether I have it on Psf or pulldown. my settings as usual 1.5 G YPrPb + Video, and the image from both outputs looks fineon a TV Logic 5.6". At home i checked SDI-A out on a 17" and it was fine.

Looks fine in HDMI at 23.98 and it looks fine when I switch to either SDI port in 1080 29.97.

What gives ?
