My guess is that it's a settings issue. I have used the Shuttle for four years now (along with other Blackmagic video capture products as part of my business) and I often experience this kind of niggle. The thing about such hardware is that the input setting for video and audio have to be set in the Blackmagic Desktop Video Utility first before making additional Preference selections in Media Express. All settings must comply with the output settings of the playback device. In the early days of using the Shuttle (over Thunderbolt in one of two Macs) I often thought I had a duff unit when in fact it was a settings issue as described above.
