You can’t ever guarantee universal compatibility on all players when using burned discs. Percentages vary from about 80% to 90%.
Some things you can do to improve your chances are:
1a. Keep your max video bit rate between 7 Mbps and 8Mbps. If the combined audio and video bit rate is close to the DVD spec limit, many players will choke when playing burned discs. 7 – 8 Mbps leaves plenty of room for audio and a “buffer”.
1b. Use high-quality blank media – Taiyo Yuden and Verbatim. Stay away from Memorex and Fuji.
2. Update the firmware on your burner.
3. Burn at a speed that is no faster than one-half the rated speed of your blank media or one-half the rated speed of your burner, whichever is less.
4. Go get a cup of coffee while you burn, and save the email reading, IM’ing and web surfing until you are done burning.
