I was exchanging tapes to see what was on a tape i had sitting in my camera bag. It was 6am and i was tired and i popped in a cleaning tape not realizing it was. So im trying ti play the tape to see whats on it. getting baffled because it only rewinds for like 10 seconds before begginning of tape. then fast foward. then rewind. then play..and this goes on for a couple minutes before i pop the tape out deeming it bad and then took the time to actually READ THE TAPE. my question is..is the cleaning tape still any good? i FFWD it all the way to the end and back to beginning several times. any flaming is fair game ;-)
