Here's the bullet...

Sony BDP-550S (Blu-Ray player) —> HDMI —> Sony KDL-40S4100 (40" 1080p LCD)

I'm playing my very first disc and I get short white horizontal lines on the left of the screen and occasional pulsing across the entire width. Remember tracking on your VCR? That's what it looks like to me! All my settings are auto except I made sure that HDMI was selected. In fact, it's the only cable connecting the two.

If I turn off 24p on the player it goes away, along with my perception of fillmlike quality

I can get things working by turning the LCD off and then back on again while the disc is playing. It's as if its not detecting 24p until it reboots.

Any thoughts?
