Today I just bought the Indiana Jones WS Gift Set and when I put in The Last Crusade it will be real clear and then fade to a real dark picture within seconds so my question is, is it the tape or is it my VCR? Should I clean the heads or just take the set back? I have had this problem on real old tapes of mine but I just bought this(I bet the tapes are still old nonetheless). Thanks. Talk about irritating.
