This program is very simple and *very* fast. It did exactly what I needed, which was adding subtitles to a Quicktime movie, and did it in about 60 seconds --- which compares very favorably with the huge amounts of time various other programs seem to require for the same task.

I did run into a problem, which turned out to be the result of an improperly formatted .srt file at my end. It would have been nice if the program dealt with the problem more gracefully than just stalling and crashing on me! HOWEVER, when I contacted the developer, I received a response almost immediately, and after I sent him my subtitles file (at his request), he spotted the error right away, and I was in business. So I, for one, am very impressed with the support for this product.
