RIT seems fine. This happens when the RIT is off. I use the RIT to make up
for the tracking error. I set it up 50Hz and everything is fine. Its not
really a problem, but I sure would like to know how it is doing this. Could
be a voltage varying,but I don't think so. I'll let everyone know if and
when I find the problem.
