Frame Rate converted / Audio track not displayed

Hi, I'm a semi-newbie to video editing but a pro-level audio editor in music. I have a video I am workinig on where I know all the original frame rates were 29.97 fps, but when some clips got edited for some reason they are now at 25.00 fps. When I drag these clips into the timeline, they don't appear to have an audio track, but when I go in to select the file and hit F to show the video and audio, it shows that they are there.If I try to drag the audio in, it won't drag. I have tried changing the video frame rate and that has not helped. I am guessing that the problem is that the audio and video no longer sync up because of the frame rate conversion to 25.00, but I'm having trouble locating the original video file and am really hoping there is a fix for this without starting again - any suggestions are very apprciated.
