It appears from:

that you sub file is not a text based sub subtitle but a VobSub file.
In that case it can indeed contain 2 languages (furthermore, it's not 
two audio channels it's just 2 subtitles languages). The subtitle should 
be loaded with -vobsub option. In your case it is automatically loaded 
because the sub file has the same name that the avi file. so the -sub 
option is wrong and useless.

Dealing with the conversion, it is not in fact a simple conversion. Your 
sub file is a collection of images containing the subtitles and should 
come with and .idx file that contains the times at which the subs should 
be displayed. In order to convert them to an .srt text file you have to 
perform an OCR on the sub file. This can be done with gocr and an 
utility present in the TOOLS section of mplayer code called subrip. You 
have to compile subrip.c yourself (see the command at the beginning of 
the file).
In addition it appears that this utility is buggy at this time (at least 
I have problems with it as as explained in a previous post).

good luck.
