Hi to all Professional,
I have face big problem with editing Canon 5D Mark II Clips using with adobe Premiere CS5.5. When playback on time line, the courser (head) stops all the beginning of clips.

Working on

Black Magic Design DeckLink HD Extreme 3D Plus
Premiere CS5.5
Wndows7 64Bit Pro
X8DAi MB
E5620 Processor X2
4 X 4GB ECC RAM
Nvidia Geforce GTS450
System on 80GB Intel SSD
Rushes on 4TB Raid for Media (02TB X 02)

In the viewer menu you need to click on playback settings and check the option not to stop playback if frames are missed.
