First, you need a 32-bit PNG in order to get per-pixel transparency. The PNG-24 name in Photoshop is a bit of a misnomer, because you can save with or without transparency. If you save as PNG-24 with transparency in Photoshop, you get 24-bits of color information and 8-bits of alpha for each pixel. Make sure you've saved the file with transparency.

Second, in CS 7, you'll want to right-click on the image in the Clip Bin and use Add as Callout, as shown here. This will composite the image as a callout on top of the Video1 track. If the image has transparency, those parts of the image should show through to the video underneath. By default, images added as a callout get a drop shadow applied to make them stand out from the video underneath. If you don't want this, you can disable the shadow as shown here. Since callouts always go on top of a clip on the Video1 track, you can use a blank title clip, or create and use a background image at the editing dimensions as the background clip on the video 1 track.

In CS 7, If you simply drag the transparent.png to the Video1 track on the timeline, then CS will fill the frame with white out to your editing dimensions and then center the image inside the frame. This is a technical limitation with the way we handle images on the Video1 track, and usually not what you'd want for a PNG with transparency. We are working to improve this for a future release.

Hope this helps.
