Since we are talking legal back-ups here..............

In reply to:

Is there any audio or video difference in quality compared to a standard dvd?




Very little if done right. DVD X-Copy is by far and away the best.

In reply to:

Also, can a burner provide dolby digital or DTS format?




Yes but it's not the burner that does it, it's the software. 1Click DVD Copy for example gives you the option of DD or DTS if they are both on the disc.

Will it be able to upconvert if played on Denon 1910 player?




Huh?
