I created a recording on my Sont handycam (w/ a hard drive)It recorded in mpg format automatically. I then imported it to my PC hard drive. I edited out all of the crap I didn't want and saved. When I attempt to burn a DVD using Nero as a video DVD I cannot select the file. I get an error message "incompatible format type". It is looking for .bup, .vob, and .ifo files. I can burn it as a data file, but then it won't play on a DVD player. How do I create the needed .bup, .vob, .ifo files from an .mpg file?
