AJA has released Io Express and Io HD version 7.5.1 drivers. These drivers address minor issues with the recently released version 7.5 drivers. For details on the release, you can consult the Release Notes document for Io Express which is available at: http://www.aja.com/pdf/ReleaseNotes_KONAv7.5.1.pdf
I am wondering if this update is compatible with FCP 6.0.6 / OS 10.5.8. I know the release notes say FCS 3 - but the release notes for the ioHD 7.1 update said the same thing, yet it is backward compatible.
I'll be upgrading next quarter to 10.6.x and FCS3 anyway, but was wondering about this update in the mean time.
