hi,
i am using edius 3 with asus p5b-mx MB, intel c2d 2.2 GHz processor, 2 gb ram, and ati x1550 512 mb display card frm past couple of months i am facing an problem with exporting when i export my video frm timeline to m2p format through procoder export for edius i've got some kind of mosaics in video file. this mosaics doesn't come frm starting it just happens frm anywhere of the video and after that when i check my project the same mosaics will come in same place where it come in m2p file. sometimes it comes in the middle of project while editing.
in starting it comes in some project but now its just started in every project.

Are you using HDV or Standard Definition video?

I had this with 3.62 recently
I re booted and it cleared. It took several attempts
I was encoding to mpeg2 using the Hardware Encoder

Forgot to say in the end it must have been a capture error
I had to re capture and it was then ok
