I'm getting blank captures while trying to capture HDMI video on a PCI-E Intensity Pro using the newer v3.5 or v3.6 drivers. The only driver which works is the v3.4, however I have audio out of sync while capturing with this driver. Tried on Adobe Premiere Pro 4.2 and BlackMagic's capture tool Media Express.
My capture hardware are two different computers, Intel C2Q + Asus P6T (latest BIOS) and Intel i5 + Asus P7P55D (latest BIOS). Both have 4Gb RAM, 2x 1Tb HDDs in RAID0, ATi 4890 video card and Win7 64 Ultimate.
For sources I used a couple Sony hardware (Bluray player, FullHD camera, PS3), a LG DVD player, a Cisco HD cable tv box, my Dell Mini (in 720p) and each computer HDMI output.
BM Control Panel is all set for HDMI input and outputs (aka default settings).
