Text Subtitles (.ASS) to PGS

[Doctor M]

Anyone have recommended software for generating Blu-ray subtitles from a text based source?

I'm getting ready to convert some custom subs for The Fighting Seabees so I can mux it and burn a disc.
I realized the software I've been using is PunkGraphcStream from 2010 and there hasn't been any updates since then.

I don't think I ever got PunkGraphcStream to work right, but sub2bd works better than easySUP in my experience:

I take it back, I realize I was primarily using GoSUP for a while. PunkGraphicStream works well with more dynamic styled subs.
Haven't tried easySUP or sub2bd.
