I'm freaking out! We had our wedding videotaped and it's on 2 discs (which are Sony DVD-R Ver. 2.0/1x-4x). They played when we first got them, but I just went to play them now (its been about 3 years) and they pull up and play for about 30 seconds then they just get stuck and quit! The discs are NOT scratched, we've hardly even had them out of the case! Are they ruined? Would it help to burn them to another DVD?? HELP!!!
