In your project, go to File > Project Settings > General and see what format of video Premiere is expecting to find on the connected device:

If this is not the format of video you shot on your camera, then change it.
If it is the format of video you shot on your camera, then make sure your camera is not down-converting the video (Down-converting HDV to DV, for example) at the firewire (iLink) port. There is an internal menu setting in the camera to turn this downconversion on or off.
If Premiere is expecting an HDV tape, and the camera is set up to down covert to DV, then Premiere will see an incorrect source.
