Does anyone know of a free program to convert mkv files to mpeg-2 files? I wanna watch MFB episode 1 subbed on my bigscreen TV but Nero 7 can't burn mkv so I'll have to convert it to an mpeg-2.

I've already googled it before, but it takes awhile to try every program out, since so many problems occur with them. I was wondering if anyone already knew of one so that I wouldn't have to search threw everything on google. Oh well...=/
EDIT: I may have found one, I'm not sure yet.

XVID4PSP. Converts everything to almost everything. I use it all the time, and yes it does convert .MKV files.
