My DVD player can handle both NTSC and PAL formats.So why is it not reading the DVD?Also what is the difference between .mpg and .mpeg video files?If my DVD player is reading .mpg files,can it read mpeg2 files.Lately my DVD burner is not recognizing CD RW or DVD RW discs,therefore I am not able to test in a DVD RW disc.Also I thought that avi filles are larger than mpg files.Whan I converted an 60MB avi fille to mpg format it became 150 MB.So how can I convert an avi file to mpg format without loss in quality? Thanks.
