DVDs: Picture gets bright-dark-bright-dark...
When watching some DVDs (maybe all; I haven't noticed it on some, but
it may not be as obvious on lower-contrast viewing?) the picture gets slightly brighter, then slightly darker, then slightly brighter, then slightly dimmer, etc. Not a flashing change, but gradual over maybe 5-10 seconds. Maybe not important, but I have the DVD player routed through our VCR to the TV. Haven't noticed any problems with playing VHS tapes or watching TV (through the VCR). Any ideas? DVD player, TV, or VCR problem? (Sounds like DVD player based on what I wrote above?!) Jamie |

Route the DVD directly to the monitor, running through the VCR causes the
'copy guard' to go into effect causing the brightness level changes. "woodpecker" wrote in message ...

It's supposed to prevent you from making a clear copy to VHS from DVD. |

you from making a clear copy to VHS from DVD. Heck, VHS inherently makes it impossible to make a clear copy... |

"William Sommerwerck" wrote in message . .. Yes, that's Macrovison copy protection. It's supposed to prevent you from making a clear copy to VHS from DVD. Heck, VHS inherently makes it impossible to make a clear copy... LOL true enough. People who are copying DVDs are using software to make perfect digital copies. The MPAA is a decade behind the times as are most things of that nature. If your TV lacks a composite input, you can get RF converters that will not exhibit this problem. If you need more inputs on the TV, switchboxes are available. |

If you need more inputs on the TV, switchboxes are available. The coaxial cable attachment on the TV (i.e. where we would hook the cable to or cable from the VCR--sorry I don't know all the correct terms!) is bad so we've been using the VCR as our tuner, then RCA type cords to the TV which has only 1 set of input jacks. (You previously gave me advice on that, James.) Thus why we have the DVD going into the VCR. Is the switchbox you refer to like an A/B coaxial switch, except for RCA connectors? Can I pick one up at Radio Shack? If I get that, will I still need the RF converter? (If so, what is that?) |

In that case get a switchbox that has RCA connectors, plug the DVD player into one input and the VCR into the other, it'll do just what you need. |
