Help info you won’t find in Books
- 1. A one-off disc is NOT the same as one pressed from a glass master.
- 2. No longer necessary to use digital tape masters.
- 3. There is no such thing as a one-off disc that is 100% reliable. The combination of blank media brand, playback drives, and authoring software produces more than 20,000 permutations.
- 4. Copy protection: CSS or Macrovision (APS) prevents copy to VHS tape.
- 5. Info Source: DiscDoctor.com
- 6. Double sided duplication is now cost effective
- 7. DVD/CD ROM double format discs duplication can be located with difficulty.
- 8. Don't create a track, slideshow or menu that you may not require - can't be deleted consistently.
- 9. Improve reliability by playing a 1 second video track, rather than a menu, first.
- 10. 3. Be sure your content will fit. Encoding quality determines maximum size. Don't plan on more than 80 minutes (not including slideshows, menus, ROM data, etc.) on a 4.7 gig DVD.

Still Image Formats

- Multiplexed into MPEG-2 stills
- To avoid square pixel, rectangular pixel distortion:
Create at 720x540, resize to 720x480 (don't bother to crop 6 pixels from 486)
- An exception for Pros: Create at 640x480 and stretch up to 720x540 to accommodate thin lines that stretch horiznontally, but not vertically)
