Can anyone explain the following for me. When I capture video and edit it on Movie Maker it saves it asa WMV file. I then convert it to an mpeg using Video Edit Magic so that I can burn it to disc using Nero. From MPEG out put on Video Edit Magic I can select MPEG 1 VCD, MPEG2 SVCD, MPEG2 DVD. What are the difference with all these - is it just a quality issue or anything else? Any explanation would be gratefully received.
