I have a Hi8 tape that I shot about 15 years ago.
I later bought a Digital8 cam just to be able to play my old Hi8 tapes.
This particular Hi8 tape have no sound on it.
I have several other Hi8 tapes and they have all sound.
I have played this Hi8 tape both on my D8 videocam and on a friends Hi8 cam but no sound on either of the cams.
I am 100% sure that there was sound on the tape from the beginning.
What has happend?
How can the sound have disappeared?
Can something be done to get the sound back?
