Where am I going wrong in the understanding on that's happening? I have downloaded a veg file that gives me 9 views at once on the screen once I have dropped my 9 clips onto them. I dragged the tracks into a different sequence & changed the start time slightly so that they opened one at a time & in a different pattern with the center one opened last. The small 9 videos all play in the preview window when I press play. At this stage everything is going just as I expected. The center video was originally a generated media file that was rendered out as an AVI file & imported as one of the nine. I wanted this center title video play at it's mall size for a few seconds & then expand out to full size so that the title was the only thing seen on the screen.

When I selected the track motion button for this center video the settings are for alpha channel with both the X & Y settings at zero & the width & height set to 720 & 576 (I'm using Pal). The outline of the clip on the grid is small & in the center as I would have expected. When I put the settings on to maintain aspect ratio & off to allow rotations & click the corner of the clip I get a small circle which when I drag changes the figures in the box on the left hand side but nothing at all changes in the preview window. If I click on the width settings & drag the figures up & down the size of the box on the grid also expands & contracts at the same time but no changes are seen in the preview window. I feel certain the problem has more to do with my understanding as to what's going on but I am unable to figure just what I should be doing instead. Any ideas?
