"Pulsating" brightness while watching a DVD
My brother just got a cable today to connect my dad's PowerBook G4 to our TV. Since we have an old TV, we have to go through the VCR and use a headphone to RCA cable to get audio through the TV. It's working almost perfectly, but for some reason the brightness pulses at fairly regular intervals (every three or four seconds). It goes between way too dim and a bit too bright. Any way to fix this?

Sorry.
<strong>There is no way to fix this. This is a copy protection scheme known as Macrovision. It has been around since the 80's or so. This prevents you from dup'ing VHS tapes and DVD to VHS. This also prevents you to use your machines in the fashion that you are.

Actually, there's some software called "DVDBackup" or some such thing. One of its features is the removal of macrovision.
Edit: I forgot to mention that the software itself, even when used for completely legal purposes, is illegal under the DMCA, so you might have some trouble finding it.

I am not convinced the problem is Macrovision. I thought that Macrovision would only affect video that was being taped as the changes in the signal were too fast for the mechanical tape mechanism to react to but the TV electronics could easily react in time to display glitch free video. I freely admit that I haven't tried this so I can't say for sure.
Just for grins, turn off all other programs, turn off file sharing, turn off the use of the network time server in the Date and Time setup area.
Are you using OS 9 or OS X? OS X should provide a cleaner signal.

You mean the thing that KaZaA advertises for all the time on my Wintel machine?

That is Macrovision. I took my DVD player to a friend's house, hadda hook it up through the VCR, got the same thing. And you can do the DVD rip to your hard drive. It'll create a disc image of your DVD that cn be played back w/o the Macrovision. Of course ya need a shitload of room and it takes a while, but...

The best way to get rid of it is to connect to the TV or home theater receiver.

No, but it looks similar to that. The software I was talking about is a freeware OS X app. Sorry, I don't remember where I got it. And seeing how it's illegal, I'd probably get in trouble for posting a link anyway.
Certain models of APEX dvd players have been able to be hacked to allow for macrovision/regional coding to be disabled, but that is the topic for a whole other thread. check out <a href="http://www.nerd-out.com" target="_blank">http://www.nerd-out.com</a> for more info on that.
<strong>oh it is definitely macrovision doing that. you need to either get a tv with AV inputs or drop about $30 into an RF modulator (a little external box that does the converting instead of your VCR)

He speaks the truth. God bless Macrovision.
