i was wondering if there is a way to convert a .ogm file with dual audio and subtitles to DVD Format with also dual audio and subtitles. like when i press the 'audio' or 'subtitle' on my dvd control it will pop up the subtitle or change the audio. and will this take up alot of space on a dvd? like if i converted a regular ogm(20 mins long) to dvd with 1 audio and no subtitles, it would be about 400mb or so, how big would 1 episode (20mins long) be if i had dual audio and subtitles?
