I have been cutting DVC PRO HD 50i footage as well as DVCAM Stuff. Using external SATA drives transferring data through a Sonnet esata express34 card.

On my old MacbookPro 1st gen It all looked great with no tearing.

The tearing i am talking about i can only really describe as being half of the previous frame or field being displayed over the top of the currant frame but at varying proportions as the video plays. You see it on cuts some of the time but mostly when the shot consists of dark to bright images or action/pans. I have tried de-interlacing footage as well as converting files from DV to DVCPRO HD 25p to see if it makes any difference, but it doesn

Thanks Jerry, I have given your idea a go, but there is still know change to the tearig in the canvas.

I had the same project on a 1st gen MacBook Pro and there was NO Horizontal Tearing in the canvas or on the 32” LCD tv I had pluged in.

I have only just had my Mac replaced in the last week to a 3rd Gen MacBrook pro where I am having this issue.

Never the less I am willing to give anything a go to fix the Horizontal Tearing problem as some of my clients sitting in on the edit are starting to think that it is some sort of effect pugin I like you use on everthing…

Once it is exported and played in Quicktime there is no Horizontal Tearing! What could the problem be?
