Hi, I have got a weird problem. My Acer laptop has a Philips DVD burner. I have been using this for more than a year to play DVD movies, write DVDs, write CD etc. overall it was working fine. All on a sudden I can not plat DVD movies anymore. At the beginning I thought my dvd burner needs to be changed but I tried audio CD and mp3 just to check and they worked fine, then I tried data DVD, that worked perfectly okay as well. I was certain that it’s a software problem. So I tried all sort of things that I possibly could. I removed the hardware and added it back on. It didn’t work. I uninstalled DVD codec and reinstall it. Still didn’t work. I installed one software called regcure, still didn’t work. I tried windows troubleshooter, didn’t get much help. Now im out of ideas. The last thing in my mind is to format the whole system and reinstall windows again which I don’t want to do. If there is any other way to solve the problem, please type it up for me. I would highly appreciate. Thanks in advance NB: when I try to play a DVD movie, it tries to read it and after a while it shows in my computer that I have inserted a blank disk, files are ready to be written.
