Comment (by edumj):

 With '''DivXMux.exe''' the subs are Ok, and it always makes Subtitle Track
 of 640x480 with any video resolution (like 720x540). May be that's why
 subs are too low if '''ffmpeg''' takes 720x576 as the sub resolution, when
 the video was changed from 720x576 to 720x540 to make it square pixels.

 There should be some way of passing '''xsub_encode''' fuction '''width'''
 and '''height''' parameters (and not let it take video source resolution)
 or just make xsubs always 640x480 like '''DivXMux''' does.
