I have an old Decklink HD PRO 444 PCIE that's does not seem to play wether with Avid or CS6 or CC. I can get SD Output in some configuations, but any hd flavour is impossible with Premiere CC, CS6 and Avid Media Composer 6.5 and 7. Final cut pro seems to work, so does After Effects and Final cut pro X... Speedgrade shows No Mercury Transmit, Davinci works.
I'm a bit lost. Any help will be appreciated.

Some of the older Decklink cards don't output 1080p. This isn't a problem in FCP as you can choose your video output independently from the sequence preset; not so in Premiere. Try creating an interlaced HD sequence and seeing if the footage will play in that.
