Did you try other tape brands? I never use Sony (Exabyte is Sony)
because they have high rewrite rates. Sony tapes are bad since
Sony introduced Hi-8.

Some years ago someone from MIT wrote that MIT is using
thousands of cartridges a month and they use cheap Fuji Video tapes
(Do not use HI-8 ) I know that US-type video tapes are worse
that european type tapes because the higher quality is not needed
for the lower resolution of the US TV system, but you may
experiment.

Two other possibilities may raise your problem:

        -       The heads need more cleaning
                To fix this you have to be very carefully.
                Open the drive and use a Q-Tip with *.
                Carefully put the Q-Tip on the head drum
                (at the point where the little heads are visible)
                Then carefully turn the drum...

        -       The * roller at the capstan drive is bad
                I had a drive where this roller had fissures
                and caused jitter.

Thanks for the reply.  As it happened, none of those suggestions
worked but I did discover the unit was still under warranty.  One
quick shipment later and I'm back in business.
