HyperDeck Shuttle Strobe Palyback

Hi

We are using the Shuttle to bypass the camera compression with the Sony FS700 camcorder.

We record AVID DNXHD MXF files.

When viewing the files with Avid Media Composer 6, we got some problems:

1. the Avid see the files as 1080i and not 1080p.
2. on playback, the footage has a strobe problem ( like you see in pan movement when shooting with DSLR)

Is there any thing to do to avoid it?

Thanks
Dori
