Best answer as chosen by user Smellslike1974: About the tape.
If it can be brought back for a reasonable amount of money, my money is on cleaning the metal, rubber and plastic rollers that do the tape handling. If that does not fix that tape issue then I know to not send it to repair but locate a replacement player or camcorder. This is my advice on that.
However I see prior discussions on the error message and it will mean the repair center and frankly repair tends to be same/more than replacements unless this is some professional model.
