in my opinion DVDs have a much much better quality than VCDs do, as VCDs are usually in MPEG file format and depends on the quality of the MPG file. If you have a poor mpg file and burn it into a VCD, its still not going to be as good as the movie on DVD. Some DVD players can read VCDs, while others can't, mainly the older versions. Most new DVD players can play VCDs. PS2 doesn't play VCDs.
