"AJA Xena LH, LHe, LS, and LSe board support" is what Sony's V11 specs say. I had asked this same question in another thread with no response. I have been using V10 with an AJA LHi with excellent results and AJA's website claims the I/O express is also supported by Vegas. V10 on Sony's site listed LHi as a supported board, and now it's not shown. So there's confusion for me too, and I don't think many forum members are using AJA cards. I've received very few responses in the past when asking about AJA support.
