Video Formats: What should I use?
Many of us out there have heard of DVDs before -- but what are miniDVDs, VCDs, or SVCDs? The reason that you may want to consider these other strange formats is because the costs of DVD burning hardware and DVD-R/RW discs themselves are still rather high.

These alternative formats provide a good economical solution for distributing your movies on CD-R/RW discs that can be played on computers and many home stand-alone DVD players.

For a complete guide on the advantages, required settings and playback options of each format, please refer to the tables below.
