I recently bought a used Hi8 Camera with paranormal nightvision mode and everything seem to be fine except when I tried it... the salesman sent me 3 8mm tapes which recorded fairly poor due to dirty heads so I cleaned the video heads first blowing air to it then I use alcohol and chamois pads and a bit of cotton swaps for the rest... but then I decided I should use try a hi8 tape and tried it... the quality was horrible with distorted lines all over... I tried the other 8mm tape I just removed and it played better and record just fine... so I thought may it needed to dry. Once again I tried the hi8 tape and nothing, tried a new hi8 tape and nothing... tried the 8mm and it works... so my question is.... why my camera doesn't like the preferred hi8 mode?
