Increasing font size on DVD

[ManOfHonor]

Hi,
I searching answer for my question, but I didn't have lucky yet. I have movie on DVD with small font. Question is: How could I increase font size without re-authoring? :confused:
Thanx in advance!

Use Pgcdemux to get the sup files.
Open srt2sup and import the sup file, change the font and save.
Mux again with muxman

I know that. I'm thinking about increasing size directly on DVD, like with DVDSubEdit (but don't have that option), by changing IFO file. Thanx anyway.
