Logic 7.01 Audio Import?, can import audio.. doesn't show up Options

Have 24 bit/48k files rather large.. live tracks from a band. About 800 meg per track. Using audio import it says its creating an overview but it doesn't show up in the arrange window except for a sliver of a graphic file at the head. Double clicking into the editor shows the file graphically and can play it but nothing shows up in the arrange window. (Strangely, even though there is no graphic, the file plays.) These files were created on an Alesis HD recorder put on a DVD and given to me. They show up as QT aif files. Saw that a track was 24/48k with big endian encoding... saved as a straight aif 24/48k out of qt but still no go.
Went to my logic supplier and tried all this on his system... same thing happened. Maybe file size limit?
Dual 2.0, 2 gigs ram.. nothing funny about the system..10.3.9 stumped. Any thoughts would be appreciated.

Gdoubleyou.. set it to auto zoom... no matter what magnification setting.. the sliver does not expand... tried grabbing it from the bottom of the wave file to expand it and it refuses to budge.. the yellow message box comes up with the name of the file, the length but nothing happens.. a mystery for sure. again, my sample editor shows the wave form but that's it.. in the editor I have "refreshed overview" to no avail. Any other suggestions?
again, the file is there but I can't see it..!
thanks,
Mak
