Since everything is going Bluray now, wouldn't it be easier to invest in a media player or cheap Bluray player that will at least playback HD from a flashdrive and output at whatever resolution you want?
If you still want a DVD, burn to DVD9 as DVD5 is much too compressed and will produce artifacts.
IIRC DVD is limited to a combined maximum bitrate of 10Mbps for the sum of all tracks: as you increase the number of audio tracks, the maximum bitrate of the video track must reduce.
Well, I don't really have money for a Bluray player right now so I dont really plan on going in that direction at the moment. But the thing is I need a program or software that will burn the DVD with the tracks. I can't just burn the DVD when the only programs I can really get my hands on at the moment will only incorporate one track. If I need to attempt to run the mkv file through multiAVCHD in order to get it to DVD appropriate quality then fine but I need a program that will burn the movie to a disc with the tracks. Perhaps I'll try converting the movie through multiAVCHD again and then burn it to a DVD with ConvertX. My only thing with ConvertX is when the DVD was finalized the movie was a bit boxy in some areas but maybe if its burning a file thats DVD quality it'll look better. If anyone knows of any good programs that burn DVDs with different audio tracks please let me know.
