Just got a game for my daughter. The game (Hasbro's Dream Life) has
yellow and white plugs that go to the A/V ports on a television or VCR,
and then the game plays through the TV.

When I connect the game directly to the TV (I have to disconnect the A/V
from the VCR to the TV to do this), the game plays fine.

But when I plug the VCR's A/V cables into the TV and plug the game into
A/V ports on the VCR, it won't play.

The manuals for the TV and VCR are of little use in describing this.
The game's manual is even worse. The TV is a JVC purchased in 1999 and
the VCR is a JVC purchased in 1996.

How do I make the game play when connected into the VCR?
