Well, I am always buying CDs and DVDs of music(mostly rock, hard or metal, usally. But, there are places out there that you can't really trust. You never know what you buy until you really try it. Quality is what I aim for, but you can't really trust anything. Never trust used stuff that they sell, you don't really know what are in those CDs. Buy all your CDs and stuff with electronics that have data that are new. First of all, the person could have deleted all the information, or at least partially, in some cheap CDs, which you can reach the data in. Most Master CDs(or the orginal that you first buy) have the data blocked, so you can't change the order or delete of the CD. But, some cheap, no good CDs don't have that program, so all the data is reachable and you could do whatever you want to the program. Also, the CD can be strached, so that can effect the data and stuff. Buy the real CD/DVD, fakes and copies are everywhere, you don't even know unless you look very closly. That once happened to me, where I thought that I bought the real thing, but it was really glitched up and sucked real bad. I was buying a copy of Advent Children:Final Fantasy VII. OF course, I bought used, because of shortage of money to actually buy a new one, plus there was no new ones in that store, which was a Gamestop, where they sell a lot of used stuff throughout the whole store. At home, I decided to use my computer, just in case anything was missing. (I don't really take chances...) Anyway, the menu screen looked quite suspicious, and the subtitles were not changing(they were in Sweedish! Who in America watches Advent Children with Sweedish subs, unless their Sweedish, when you can put it in English...). After, I decided to change the language, but the language was not changing, no matter what I was doing. Going from player to player, each reply was the same. "No language option." So, I ended up watching the whole movie in Japanese, which was okay, with these huge subtitles that went whack at about the end. Also, half of the scenes didn't load and the ending credits rolled halfway, then suddenly stopped and then the backround graphics went all squarey and the names didn't even roll. I was like "What the hell?!" and then I decided to try to fix it. I went into the files, which was not supposed to happen, I figured out, after having to try with my music CDs(artists like Weezer and Fall Out Boy). There was an empty audio folder, which I thought that someone deleted or cutted out the English audio. Then, the film was next. All there was was some unopenable files, all in this small folder. The letters made no sense, so what was I supposed to do?
