Actually it looks like if you sync via Avid Satellite Link, you can scrub. But you can't if you sync via MTC (dumb).

"Video Sync offers seamless playback of movies in sync to MIDI Timecode & MIDI Machine Control. It works with all major DAWs including Pro Tools®, Logic Pro X, Nuendo, Cubase, Ableton Live!, Bitwig and Studio One - or any other device that can generate MIDI Timecode as a source.

Enjoy the tightest possible sync integration with Pro Tools|Ultimate™ & Pro Tools|HD™ using Satellite Link - for incredibly accurate scrubbing, selection, looping & moving in any direction in the timeline, or within Pro Tools® - while the picture constantly updates.

Video Sync's sync engine provides stunningly fast lock-up times and guaranteed tight sync - in many cases, better than the video engine built into your DAW."

Hope you're up and running smoothly!
