I keep hearing about the next format wars being HD-DVD vs. Blu-ray. What's the difference? Is one of them clearly better? Which format is Apple supporting and which one will probably win? I just think it's dumb to have new formats for movies and games already. DVD just became the standard not too long ago. Do we really need to have a new format, let alone two? Even if one of these catches on, they better be able to play all my DVDs.
