BDSup2Sub v5.1.2

BDSup2Sub was written initially to convert capitons demuxed from a Blu-Ray transport stream (M2TS) into the DVD VobSub format (SUB/IDX) used by many DVD authoring tools - hence the name. Many more features were added over time as was support for other formats. So in the meantime the name seems a little inappropriate. In a nutshell, it's a subtitle conversion tool (for image based formats) with scaling capabilities and some other nice features.
