Daniel,
First off VCDs are bootleg unauthorized copys and completely illegal to sell or buy.
Secondly, these DVDs should look great (for $20) and VCDs generally look like crap (VHS quality or less). So even though most of these Disney DVDs should have been 16:9 enhanced, I'll gladly pay the extra $7 per disc for the considerably better audio and video quality and piece of mind.
Bootlegs only contribute to these higher DVD prices, fewer available titles, and lack of 16:9 support.
