I just downloaded ffmpeg 0.4.9 pre. I then downloaded MSYS and MINGW. How do I set it up so that I can use it? do I have to start a command prompt, cd to the director of Msys, run Msys, and then cd to the new directory of FFMpeg? And once I get it running, what is the command I should enter to convert wmv and avi to dvd compliant mpeg2s? Thanks.
