I have just started to burn dvds for the first time but am having a bit of a problem.I burned an mpeg file to dvd no problem, but then tried to do the same with a divx.avi file.The process completed but when you put it in a dvd player its just says wrong disk or file format not supported.What fgile extensions do you need to have? and do you need a converter to do this or can you just change the file extension by renaming it?I have been using roxio easy media creator basic dvd home with which to do the burning and I don't thinkit converts the files for you.Thanks.
