It hard crashes, like application box pops up and says "Scenarist has experienced a fatal error and has to close. Please send report to Microsoft" blah blah.. the hard Windows crash type. Far as my Scenarist installation being borked, I don't think so. I use it all the time for DVD2DVD-R and DoItFast4U/DoCCE4U and it works fine. However every movie I have tried with DVD2SVCD has crashed Scenarist.. both with subtitles and without, although subtitles crash Scenrist on input whereas without, Scenarist crashes when building the DVD video. Thanks
