[net.video] VCR Problem with Prerecorded Tapes

halle@hou2b.UUCP (J.HALLE) (02/17/86)

I recently got a top-of-the line VCR which is giving me problems when
I try to play prerecorded tapes, ie those with a "copyguard" signal.
The top of the picture is skewed hard right.  External adjustments
don't work.  Any suggestions?  Relevant diagrams below.

It's not your VCR, but your TV.  Many older TVs displayed the skew problem.
I have heard (and seen) problems with Zenith TVs.  I was at a friend's house
to get a Commodore 64 hooked up to a Zenith color TV and it would always roll.
Why?  Because the output of the C64 is NOT full NTSC compatible.  Zenith TVs
have been known for wanting exact sync and sync timing.

So, your only choice is a new TV.

Yes, write a nasty letter to whoever recorded the tape; this is one of
my pet peves.  The problem is called "flagging" and lies with the tape
and not with your recorder.  Of course the video tape company will say
it's a problem with your TV.  I no longer buy pre-recorded tapes for
this reason.  I wait until they are on cable and then record them.

I have used my VCR (Panasonic PV1275, a low-end two head machine
about four years old) with a 1970 Zenith TV, a 1970 Toshiba, a 1975 GE,
a 1976 RCA and a 1985 Hitachi.  With tapes I have made, no flagging
on any TV.  With some prerecorded tapes, flagging on the Zenith only.
I second (third?) the comment that older Zenith sets are fussy about
horizontal synch.

I have a Sanyo 7250 (el-cheapo) Super Beta which exhibits picture flagging
on the *very* top (about 15 scan lines).  My Sony's do not.  Am I correct
that this can be adjusted?  Or will the service person just say -- sorry,
get a new TV....
