Daniel Sofie,
I know where you're coming from and because vcrs are so cheap nobody
will pay to have one fixed anymore.

I know this technique works perfect for me in all 3 of my vcrs. I
record and play tapes and they all play perfect no matter which vcr is
used for the recording.

The things you mentioned seem to date back when vcrs cost hundreds of
dollars, not $69 for a 4-Head HiFi. This can help people save $69 if
they wish to take the time to make the adjustment. What do they have
to lose?
