Slideshow is sized wrong after import as asset. need help

Question

Hi all, I have a strange thing happening with a project. I have PPO 5.0.  My project settings are HDV and my computer is:
Platform: iMac 2.66 GHz intel core i5, 8gb memory. OS: 10.6.6
I have about 2 hrs of footage that's fine. I wanted to add a Quicktime slideshow (.mov) as the last chapter. I imported the slideshow as an asset, then dragged it to the timeline.  in the viewer it is now letterbox size when it should be widescreen!
Previewing it with Quicktime shows it displayed as widescreen just fine.
The properties of the .mov file are:
dimensions:  720 x 486
codecs:         H.264 high efficiency AAC
color profile:  SD 6-1-6
duration:  11:35
audio channels: 2
total bit rate: 1,934
On my timeline, the viewer settings are "fit" normally.  when it comes to the section where the .mov file is, it is still "fit" but the screen is now very small.
ON THE TIMELINE if I click on the clip, Properties are:
File Path: /Users/n.../Documents/Adobe_mywork/Disc2/myslide.mov
Type: MPEG Movie
File Size: 161.1 MB
Image Size: 720 x 486
Pixel Depth: 32
Frame Rate: 29.97
Source Audio Format: 48000 Hz - compressed - Stereo
Project Audio Format: 48000 Hz - 32 bit floating point - Stereo
Total Duration: 00;11;35;14
Average Data Rate: 237 KB / second
Pixel Aspect Ratio: 0.9091
Why does it display as letterbox ?
I need this thing to be widescreen just like the other footage. please help !
thanks so much!
