My PS3 has been occasionally dropping frames for either the left or right eye during playback of Blu-ray 3D movies ever since the last system update. I've changed the HDMI cable but that didn't work. I have the Slim PS3 hooked up to my Onkyo HT-S5300 receiver and passthrough the video from the receiver to my Panasonic GT25 3DTV. I have 24 hz output turned on for the PS3 and 24p Direct In turned on for the GT25. The issue doesn't resolve itself whether or not I bitstream the audio to my receiver. This doesn't happen during playback of 2D Blu-rays.
