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

[makaala]

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.
