I started using mkvtomp4 about 2 years ago... It's a GREAT tools to convert mkv to mp4!!! all the audios and subtitles are optional on my iOS devices and it make their m4v just like the m4v bought from the iTunes!!! And, from 0.218 to 0.223, awesome updates added to this software.

but I wanna post some suggestion about the tool for the nice developers~~

a. If u convert the 720P to 480P with subtitles, the subtitle will move to one side of the screen but not in the middle of the screen.

b. Could u add 540P support? Or just let the users to decide the resolution...

and I will continue using this tool, and if there is any other to suggest, i will add them here...

I hope the developers can see this and make mkvtomp4 better and better!!!
