Error coverting to ps3

I get a weird error converting to ps3. I choose the ps3 profile with subtitles and just raise the bitrate i little. The finished file only has sound when i play it on the ps3 and when i watch the file in vlc everything seems fine until the subtitles appers, then the scrren is black and i only see the subtitles and when there are no subs i see the picture fine.

Pleez help me.

edit: i use dvdfab platinum
