In my experience using a BMD Intensity Pro on a Windows 7 PC I could only capture .AVI wrapped codecs,
Then when capturing in Premiere Pro CS6 I had an extra option of capturing in DVCPRO HD, as I recall it was the story that Windows system can’t capture anything else, it must be so though (when using BMD cards, because you didn’t have an issue with AJA as you mentioned),
[Myra Riddick] ” I can output video but am having a hard time figuring out why audio is not reaching the tape”
As for that issue I would recommend looking at the output settings on either BMD’s Media Express or Premiere Pro, to make sure the audio is being assigned out, maybe it is being output through somewhere else, I know BMD cards to be flexible that you can output audio one way and video another.
