    Need some codec/format insight


      I've been doing some trial and error searching for the best output formats for various purposes and I'm a little confused.  Can someone explain why certain exporting as certain formats like MPEG4 and sometimes MPEG2 generate multiple files?  Is it splitting audio out separately or creating some kind of index files?  I don't really get it and I'm not sure how to use them or if I should.  Also, what's the difference between all the MPEG2 formats?  I see MPEG2, MPEG2 DVD, MPEG2 Bluray, and MPEG2 MXF.  Delivery platform for my current project is YouTube.  Can someone help me understand these MPEG fomats?  I'd greatly appreciate it.
