I'm using Ritek G03 dvd-r's. I made a couple of backups, and just for the hell of it, I put cd stomper type labels on the dvds. Now those 2 dvds have random lockups. Is it wrong to put cd stomper type labels on dvd-r's? I haven't had any problems with any other games that I've backed up. I have a v4 ps2 with a dms3 2.0 modchip installed.
