Need Help Fast Re: Problems with capturing in Adobe Premiere Pro CS4

I am working on a project with a deadline.  I am using Adobe Premiere Pro CS4.  My camera is a Sony Digital Video Recorder DCR-HC26.  My computer is a Dell with OS of Windows Vista.  I have been capturing numerous clips from hundreds of mini digital video cassettes.  Yesterday, I attempted to capture from a Radio Shack Mini DV Metal Evaporated mini DV digital videocassette.  For whatever reason it will not capture.  I have never used one of these tapes before.  Could it be the tape?  After I click on "Capture," the screen shows NO PICTURE of sound, however, it plays on the camera.  It can't be the camera settings because all the other tapes work. . .  Any advice?
