1. Use your cd/dvd burner and make sure that the firmware is the latest for your model.
2. Nope, slow speed does not necessarily mean a good burn. Burning good discs is a result of firmware/media/burner cooperation.
3. Most burning software can burn a cd correctly, however not many, if any, offer the support that you can get from ImgBurn.
4. Always verify your burn to make sure that the data you have on your source is what you get on the final product.
5. Start with your newest unit.
6. Longest media life is determined by the quality of the disc manufacturer that you choose. I prefer Taiyo Yuden cd's myself.
