I'm trying to convert some movies so I can play them through moonshell or something, and I hear only DPG is a compatible video format... So I go looking for those. All of the movies i've been finding are over 500mb.... But that's too big. How do I get a smaller sized .dpg file of movies like Avatar or Harry Potter and the Half-Blood Prince? I want at least 3-5 movies on my DS at a time even with the 2GB Micro SD card I have being almost/mostly full.
