Ok, here's the scenario:
Live event capture in 1080i (have tried both DVCProHD and ProRes). Capturing using VTR XChange.
Everything looks good.
When we try to play it out in SD it has weird interlacing going on, mostly visible with movement on the video. We have a second server that seems to play it out ok. Both have LHi cards with the same software versions etc. Could it be the card or maybe some hidden setting?
