The only way to properly convert a Mac Postscript or TrueType font to PC will be Fontographer, and (to my knowledge) it *is* still available - it just hasn't been updated for a long time. It's a bit expensive, but it works like a charm. The TTConverter is nice, but it fails with an awful lot of fonts, where Fontographer (again) will handle it.
