I recently uninstalled and then re-installed my Production Premium version of Premiere Pro CS3 because it was unstable, and that approach worked for me in the past.
However, when I recently re-installed PPCS3, the new project menu displayed differently (see attachment), and I'm not sure what's going on. Typically, if I wanted to choose an XDCAM format I would twirl down that option, and select 1080i, 1080p, etc. Now when I open the New Project window, 1080i, 1080P, etc are all top level options that don't require any twirling into.
I'm on a MacBook Pro running Tiger with 4 GB or RAM.
Any ideas as to why this is happening, and how to fix it, will be greatly appreciated!!
It appears that your attached screen-cap did not make it. Try again, and use the little "camera" icon in the middle of the toolbar on the editing screen, and not the "Attach File" box at the bottom.
I have not heard of anything like what you are experiencing. Maybe with the screen-cap, others can recognize the issue.
