CS5 – BM Decklink SDi – Unable to get accurate deck control

[Christopher Lowden]

Hello
I am running CS5 Premiere Pro on a mac 10.6.4 with a BM decklink SDI 7.9. I am unable to get an accurate deck control using RS422 with Premiere. Even if I change the frame delay, I cannot get a regular edit point. I do not have this problem on the same digibeta recorders driven by Avid. I presume this is not normal and I hope I am not alone. Does anyone know what can be done?
Many thanks
