Sorry typo: firmware.
Check with the manufacture if the latest update for your burner is installed.

If you have a NVidia videocard change the 3D settings to “Let the 3D application decide”.

What codec does these avi’s use?
If its divx they could be the problem.

Is your fireware up to date?
Make a iso and burn with e.g. Nero.

There is this nice new feature in CS5.
Drag your footage to the New Item Icon in the Project Window (like in AE) and Premiere will create a matching sequence.
