The 10.5.1 update, and Front Row...

[Arkanok]

Prior to updating to 10.5.1 (just 10.5), I used Front Row constantly and it worked perfectly. No freezing, no glitches of any kind, at least for me. However, once I upgraded to 10.5.1, every time I load up Front Row, no matter what I'm doing, after just a few seconds the screen goes blank, and the little light on the front of my MBP goes on as if the computer is prepping to go into sleep. If I play a movie file from within FR, it does the same thing, except since theres a video playing, it turns the screen back on, only to keep repeating itself every 10 - 15 seconds.

Is anybody else experiencing this?

So, nobody is having this problem?

No, Front Row works fine on my iMac...

I had this exact same problem on a fresh install of 10.5, but after updating to 10.5.1 it doesn't seem to happen anymore.

Also in settings I disabled the ability to have the screensaver turn on. Try that as well.
