Whats the best subtitle software out there for increasing font size ? I'm planning to covert mp4's (with soft subtitles) to dvd's, but the problem, there too small on the big screen. I've found http://www.aegisub.org/, but i think this only does "per-subtitle" basis, and not all at once, which would be a real time saver.. Since the result will be converted to dvd anyway, playback shouldn't be a problem. any suggestions?
