Well, I got a couple burned dvd's a while ago. I tried them on my PS2 and they worked for most part, but after a certain time period of watching them, they would start freezing up. The time between the freezes decreased all the time, until it froze constantly, and I got the message "Unable to read disc". So, I tried the discs on my PC as well, thinking that it was my PS2 that was the problem. I try them there as well, and the same thing happened, constant freezing up. However, the time at which this constant freezing occurs changes, and I am bewildered by this problem. Does anyone have any ideas on why something like this would occur and how I could possibly solve the problem? Thanks in advance.
