V7-V9 difference?

[mitsos79b]

oh, 3 more questions

1. Assuming that I want to put messiah and not dms, should I wait for them to het v.1.33s? or will I be fine with even earlier versions? like the 1.31 they have now?

2. When I burn to an image, first I burn the image to a cd-rw so that if an error happens, I won't have to throw away the cd. Would it work in the console if I placed the image of a game in a cd-rw or dvd-rw (depending on the game) and tried them in the console first, before making a cd-r or dvd-r?

3. In what format do you prefer your burnings? dvd-r or dvd+r?
