I recently updated (so they call it) to WMP10 and now nothing (audio or video) plays. Every file played fine in version 9, but now they all come back with error: "C00D1199: Cannot play the file." They all play fine in Real Player, but I prefer WMP (I know, "what a dork"). I've updated my nVidia driver and DirectX, I've re-installed WMP 10 numerous times, and I even somehow figured how to roll back to WMP 9, but I still get the same error. My eyes are going blurry trying to find a post with the same problem, so feel free to direct me there if this problem has already been solved. Thanks for any help you can offer. -Nedry :cheesy:

You could try reinstalling WMP's codecs from here:

Or give this a go:

I've updated drivers, codecs, and quadruple checked the speakers setting. I don't believe I'm doing these things incorrectly and I've read the chrisl page 15 times. I think there's some conflict between my cards and the updated WMP 10. If things (both audio & video) play fine in Real Player the cards are apparently working correctly, right? A couple weird errors as I've been screwing around, Win DVD won't play a DVD disc anymore, WMP10 pops open when I try to open WinDVD and I get the error: "Windows Media Player cannot play the DVD because a compatible DVD decoder is not installed on your computer." Also, when I'm doing the (Tools | Options | Devices | Speakers | Properties ) speaker fix, the "Audio device to use" choice box is empty. I can't pick any device to use. Again, any help would be great, still dinking away with drivers and devices...thanks.

Here's just a follow-up to a very arduous fix. WMP 10 somehow corrupted some files deep in XP , and the Gateway people couldn't figure it out after about 10 hours, so I ended up re-installing/repairing XP itself. I was told to back-up "My Documents" and "My Pictures" as there was a good possibility that the repair would erase those folders, fortunately it didn't, and when I reinstalled WMP 10, it had a difficult time finding a couple DLL files, but I searched the computer and moved them to the desktop and pointed the install process there, and everything played, but I still couldn't hear audio in WMP, although I could see it playing and wasn't getting an error anymore. I fixed that with a codec pkg install, and everything seems to be working okay now. Thanks for all the help, and I sure hope nobody else has to go through that hassle.

...and thank you for taking the time to come and tell us about it. Really glad it's fixed for you and I'm sorry we couldn't be the ones doing the fixing on this occaision....
