capturing problem, please help.

[kees44]

I hava a capture problem with a video tape, i have a serie of laurel and hardy i want to set to dvd, al the tapes captured without any problem, but one of them gives problems, the view of the tape shows a sometimes jumping part of the picture like a moving head, is jumps back it is like a replay of a part of a second, I can,t capture because it drops a lot of the frames, maybe some security or something, the picture is good and the tape is not damaged.

thanks for your help, ps capturing trough tv broadcast is okee .
