Burning Video Discs:
Burn can create four types of video discs. VCD is the first digital video disc format. After that came SVCD which has a higher resolution. Then came DVD-Video discs which are now the common way to distribute digital video. A lot of the modern DVD-Players can play DivX discs. This format is especially popular on the internet. DivX files are often a lot smaller than MPEG2 (used on DVD-Video discs), but still look and sound reasonable.
