To get a better idea of what might be going on can you be more specific of typically how many clips you get from a one hour tape? Do the number of scenes you have recorded on a tape correspond to the number of clips imported?
If for example on a one hour tape you have recorded ,say ,35 scenes ( record button pressed on and off 35 times)
then are you saying you get 35 clips into FCP? If you get 35 clips in this instance then as Luis says, that is how it should be. If you are getting more than that number ( gazillions ?), in this particular scenario , then obviously something is wrong.
Sometimes using a camcorder to play back tape that was not the original cam' that recorded it can cause import issues.
Also if the cam' recorded at LP instead of SP then again problems can occur on import.
One and a half hours of video on an "hour" tape would indicate LP mode.
Have you tried to clean the tape path and imported a tape to see if it makes a difference?
As Luis says, try QTP, but if you really are getting "gazillions = a huge number" of clips per tape then something might be going on that QTP can't even overcome.
I can understand that if you are getting a huge number of unexpected scene breaks then editing out the first second of video with missing audio may not be practical.
I would be curious to see if a short import into iMovie results in same issue or not.
