I run Windows XP SP3. I don't play DVDs on my computer often, maybe a few times a year. The last time was probably about 3 or 4 months ago, and it played without incident. Last night I tried to play a DVD and it won't play.
I have several programs that should be able to play DVDs: Windows Media Player ver. 11, Real Player 11.1.1, GOM Player, Nero 7 Showtime Essentials, etc. None of them work any longer. I am not aware of any changes I've made in the interim. When I run "DVDUPGRD /Detect" it detects Nero.
I have always had Autorun turned off. Up until now I would put a DVD in the tray, go to My Computer, click on the drive and the DVD would start playing in Nero -- I've associated DVD video with Nero. Now, Nero comes up but only the controls are present. It doesn't really hang, because it's responsive as far as pulling up the list of options and clicking on the "X" to shut it down, but it won't acknowledge that there's a DVD in either Drive D or E.
When I try to play the DVD with WMP it tells me it cannot play DVDs (it used to play them just fine). It makes some generic suggestions about the screen settings (I haven't changed them since the last time I played a DVD) and it tries to get me to subscribe to Napster.
When I try to play with Real it opens and the control panel at the bottom indicates that it is playing a video, and can toggle between "Play" and "Pause" but it only displays ads for Rhapsody, etc. GOM tells me it needs a codec -- I believe I already have one (see DVDUPGRD). Anyway, I tried the one they suggested and it didn't work, so I uninstalled it.
On a thought I ran Nero and had it check for updates. It found some. In the process of downloading and installing the updates it actually managed to wipe itself off my computer. Fortunately, I still had the original CD and reinstalled it. Even so, I had to go back in and reassign all my file associations.
Everything else about Nero seems to work. I can copy a DVD (a home-recorded DVD without any copy protection, of course) but I can't play one.
EDIT: I should also mention that I have tried several different DVDs, including some that have played successfully in the past. Neither of my two DVD drives will play them. Both drives are less than 2 years old. I don't think the problem is related to either the DVDs or the drives.
