RE: D1 control track problems

Funny you should mention that... but please be more specific re machine
and tape types.

I encountered that problem on a DVR-2100 which was recently checked
out, so tensions, etc. should have been OK.  Error was actually flagged
during REC as the confi heads noted the CTL problem, but kept on recording.

Retried recording and problem showed up in same place (actually many random
places, but repeatable) so I assumed it was stock. A SONY tape was fine.

However I later tried the 3M in another machine and it recorded OK over the
same trouble spots.  A little disconcerting, but it never showed up on a SONY
tape, so I am still suspicious of the 3M tape.  (Obviously, any 3M problems
will resolve themselves very shortly!)

Look for heavy breathing of CTL level on WFM; may indicate guide setup / 
tape edge problems (stock or machine).  [if heavy breathing is persistent,
listen carefully for sighing, moaning or squeaking in the tape path].
