Have you mixed tape brands? Particularly top-end Panasonics with

*anything* else? Problems with this were more common than

they are currently (with the exception of the combination noted

above), but it could still be an issue. If you do use a cleaning tape,

I often recommend the following: use a cleaning tape of the same

brand as what most of the tape used was; use it ONLY in VCR

mode; use it for 3-seconds on the first pass, wait 30 seconds for the

heads to cool, then use it for 5 seconds, wait 30 seconds again, then

use it for 7 seconds (care is needed if there is any possibility for

"varnishing" from heat - and if the heads are dirty, varnishing

resulting from heating of the residue is a distinct possibility [I've

done it...]). Overuse of a cleaning tape with Mini-DV/DVCam

can itself destroy the heads - use it sparingly. If this does not solve

the problem, repair is likely necessary. BTW, the most trouble

I've had with worn transports has been with recording over tape

recorded at one speed with recordings made at a different speed.

Generally, rerecording at the same speed results in fewer problems

with worn transports. It sounds like a worn transport may be

the cause of your problem, though...
