Another Media Question

[fatsbrown2]

Ive read a bunch of posts about getting quality media- ive heard riteks were good in the us- i have 2 questions-

1. for playstation 2 backups- does the speed matter when purchasing good quality media- will a playstation game burn better on a 4x dvd instead of a 2x-

2. i also want to burn dvd movies- again, is the quality of the media as important as playstation, and is the speed ie. 2x, 4x determinative of the quality-

i was assuming the 2x or 4x just determined the burn speed, and not the quality of the media- im new so i get a little confused when reading some posts- thanx- chris
