Installed RC3 last night and am really happy with it. Fast and clean. Today I installed the new Flash 10.1. I launched Flash Showcase to test. Audio is starting late and running slow with low pitch. It's like the audio is running at 1/4 speed vs. the video. I tried both CNET TV and Sony movie trailers.
I killed every optional running process with SETCPU in performance mode at 1200 Mhz using Chevy's Froyo 1.2 kernel.
