8mm Tape stops when rewinding

I have a Sony 8mm camera that works fine with most tapes. A few tapes stop when rewinding in the middle. I also have a tape that will play forward and rewind only to a certain point (not the beginning of the tape). The camera thinks it rewinded to the beginning because the tape icon shows full. Is there a way to rewind it to the beginning?

What would be the cause of other rewinding problems? Is there a place that I can send these to, to get fixed and/or fixed/transferred to DVD's?
