Multiple PIP and PS3

[bbjay]

Hey Guys, I am working on a Blu-ray project now that utilizes a main video-1280X720 AVC 23.976 and 2 SD-PIP streams- 720X480 AVC 23.976. I am having difficultly getting both PIP streams to playback on a PS3. Only my first PIP stream will show up. It does work correctly on some other Profile 1.1 players, but the delay is about 5 seconds to switch between the two. Has anyone seen or know of any other Blu-ray disc that have multiple PIP and whether or not they playback correctly on a PS3?

Thanks,

Lucas
