First you should know there’s no such thing as a DVD which will play in all players. You can do things to improve compatabilty:
1. Keep your overall avg bitrate below 7.0 Mb/s Remember Less is better in DVD. Use CBR if possible to avoid bitrate spikes which all encoders have.
2. Always use AC3 Audio – PCM/AIF takes alot of bandwidth which may throw you over the top which is 9.8 mb/s
3. Use good quality Media
4. Don’t use DVDSP layered menus!
5. Don’t use DVDSP slideshow functions – make any slideshows manual.
6. Burn at the slowest speed possible – some might argue this
7. Don’t use paper labels
Good Luck
