Scenarist error with importing sub's

I'm trying to backup Mr.Deed (PAL-edition), but I keep having troubles when importing my subs(ripped with subrip 1.17). It keeps giving me this error: ------------------------------------------------------------------- PixelArea: Top=0, Bottom=576 SubTitleImage: Width=720, Height=576 Info *******Error******** ------------------------------------------------------------------- I've got no idea what it can be, because I've only just started with the whole scenarist 'thing'. I re-encoded my video-stream with CCE(used the 'Getting the best from CCE' guide, with DVD2AVI & VFAPI) and so got my audio streams from DVD2AVI. Does anybody recognize this problem or can anybody explain what in God's name it means.

PAL subpictures are limited to 573 lines.

Thanks for sharing this vital pece of information, but I kinda solved it myself with just some messing around in the .sst file. I now know which size is good to use. Thanks anyway.
