mkvextract comes with megui doesn't it? It is in my tools folder in my megui folder. http://sourceforge.net/projects/megui/
Installing the fonts should fix the problem when converting. If not then your program sucks for subtitles.
Also learning to encode things manually with megui instead of bothering with converting programs does wonders. Although its more complex and may vary from anime to anime. Read up on some aviscript. Choosing your own file size is great. Adjusting settings to adjust quality to meet your needs.

Why are you converting clannad to avi when it was released in avi as well?
