All to often the any problem with a Matrox board and software can be traced to the Matrox. My only suggestion would be to remove it all and see if the problem still exists.
Edit: Oops I just noticed you are not using Premiere 4.1, try upgrading to that first.
Have you ever upgraded Adobe Premiere Pro in the middle of a project?
By the way I captured the same clip in Adobe software only mode using HDV as a capture settings. The editing mode is Adobe HDV 1080i, 29.97 frames. The results are also jerky. When I render the clip captured it is also very grainy??

Thanks for responding so quickly!
Performed all updates to CS4 Production Premium. All is well. I am also using the H.264 codec and creating my project in Encore CS4 as an H.264 format. Much cleaner!
Good news, and thanks for reporting.
BTW Did you update your Matrox drivers to the newest version for CS4.1? If you did, was this a beta, or a release driver? There have been conflicting reports, and I just wanted to find out the current status of their driver for CS4.1.
I updated to Adobe 4.1 non beta. This is also to support Matrox's RTX2 non beta 4.1 drivers.
Thanks for that info. Someone done the way will benefit from that.
