Playing DV footage that was recorded on a different...

Hello,

I own a Canon XL-H1 HDV camera and I recently tried to play back some DV footage that was recorded on another camera (I think it was a Panasonic??).
The problem I'm having is that I can view the footage but the audio is not coming out (there is occasionally some but its choppy and infrequent.
I've tried playing around with the audio settings but I'm wondering if the Panasonic camera may have had a different setting that my Canon can't recognize.
I no longer have the other camera, just the tapes.
Is there a way I can play them back or import them into my computer (I have a MacBook Pro with Final Cut Express).
