In the last 2 weeks, my Playstation2, which my boys use extensively, has been having trouble reading movies. Most PS2 games read okay, but occasionally, it will refuse to read a game too. It was bought when it first came out. Any advice? I've always thought those commercial cleaners are all gimmick and no substance, but if you can recommend one that worked for you, I'll give it a try. I did buy a can of compressed air and sprayed it in there, which seemed to help for a day or so, but now the problem is back.
