即使在我们使用Windows 7 和Windows 8的现代(Windows 8)计算机时代(computer age)，您在尝试观看时仍然会收到诸如“Windows Media Player 无法播放此 DVD，因为数字复制保护存在问题”之(“Windows Media Player cannot play this DVD because there is problem with digital copy protection” )类的错误，这不是很好吗？您计算机上的Netflix常客？考虑到人们在计算机上观看DVD(DVDs)非常普遍(VERY COMMON)，这样的事情不仅“起作用”，这真的很痛苦！
无论如何，这件事昨晚发生在我身上，我花了大约 20 分钟来解决这个问题，所以我想我会写下我最终是如何解决它的！希望您在认为(Hopefully)Windows或您的DVD 驱动器(DVD drive)等有问题之前阅读此内容，因为我看到有些人因为这个错误而重新安装Windows或获得新的DVD 驱动器！(DVD drive)
实际上，问题都归结为一种叫做codecs的东西。编解码器是可以对(Codecs)DVD上的材料进行解码的小软件。每当创建DVD，尤其是安装了版权保护软件的新 DVD 时，都会使用算法将(copyright protection software)DVD的内容编码为特殊格式。此编码数据无法以正常格式在您的计算机上播放，因此必须在播放之前在您的计算机上对其进行解码(DECODED)。
您可能听说过DivX，它是一种编解码器，可以让人们将完整长度的DVD(DVDs)压缩到 CD 上，而不会损失很多原始图像质量(image quality)。一些软件DVD播放器会为您自动下载所需的编解码器，因此您不会遇到此问题，但由于某种原因，Windows Media Players对此很烂，并会弹出错误消息(error message)。
如果您有蓝光驱动器并尝试在Windows Media Player中播放蓝光光盘，则同样适用。默认情况下， Windows Media Player(Windows Media Player)无法像DVD那样播放(DVDs)蓝光(Blu-ray discs)光盘，因此您必须安装正确的编解码器才能让它们在Windows Media Player中播放。
您可以通过访问Free-Codecs.com 并下载X Codec Pack 或K-Lite Codec Pack来下载几乎任何类型的视频格式(video format)的所有编解码器。您会看到它们都列出来，一个在第一页，另一个在第二页。只需(Simply)忽略所有已过时的灰色项目。
如果您运行的是Windows 7或 Windows 8，我的建议是继续在您的系统上安装K-Lite Codec Pack 10.xx Full、Standard和Basic 包(Basic package)。此编解码器包也支持 64 位，所以不要不必担心K-Lite Code Pack 64 位(K-Lite Code Pack 64-bit)，因为它的开发已经停止。
您也可以为Windows 7和Windows 8安装X Codec Pack，但K-Lite似乎是更受欢迎的选择，下载量接近 2.47 亿！如果您的系统上有足够的空间，我建议您安装Full code pack 而不是Standard或Basic。这样你就可以播放任何你扔给它的视频文件，而不必担心以后安装更多的编解码器。
至于蓝光(Blu-ray)驱动器和光盘，如果Windows Media Player即使安装了编解码器也无法播放光盘，您可能必须尝试从 VideoLAN 安装 VLC(VLC from VideoLAN)之类的东西。实际上，如果您不介意(t mind)安装VLC ，在安装编解码器包(codec pack)之前先尝试使用VLC播放光盘可能是值得的，因为VLC无需额外软件即可播放多种格式。此外，请确保您有一个可以读取蓝光光盘(Blu-ray discs)的驱动器。享受！
How to Fix Window Media Player "Cannot Play This DVD" Error Message
Isn’t it great how even in our modern compυter age with Windows 7 and Windows 8, you can still receive an error like “Windows Media Player cannot play this DVD because there is problem with digital copy protection” when you’re trying to watch a regular from Netflix on your computer? It’s really a pain that something like that doesn’t just “work” considering it’s VERY COMMON for people to watch DVDs on their computers!
Anyway, this happened to me last night and it took me about 20 minutes to fix the problem, so I thought I would write up how I ended up fixing it! Hopefully, you read this before thinking it’s some problem with Windows or with your DVD drive, etc as I have seen some people re-install Windows or get a new DVD drive because of this error!
Actually, the problem all comes down to something called codecs. Codecs are small pieces of software that can decode the material on a DVD. Whenever a DVD is created, especially new one with copyright protection software installed on them, the content of the DVD is encoded using algorithms into a special format. This encoded data cannot be played on your computer in its normal format, so it has to be DECODED on your computer before it plays.
You may have heard of DivX, which is a codec that allows people to compress full-length DVDs onto a CD without losing much of its original image quality. Some software DVD players will auto-download the required codecs for you and hence you won’t have this problem, but for some reason Windows Media Players sucks at this and will pop up with the error message.
If you have a Blu-ray drive and are trying to play a Blu-ray disc in Windows Media Player, the same thing applies. Windows Media Player, by default, cannot play Blu-ray discs like it can DVDs, so you have to install the correct codecs to get them to play in Windows Media Player.
You can download all of the codecs for just about any type of video format by going to Free-Codecs.com and downloading the X Codec Pack or the K-Lite Codec Pack. You’ll see them both listed, one on the first page and the other on the second page. Simply ignore all the items that are grayed out as they are obsolete.
My suggestion would be to go ahead and install the K-Lite Codec Pack 10.x.x Full, Standard, and Basic package onto your system if you are running Windows 7 or Windows 8. This codec pack supports 64-bit also, so don’t worry about the K-Lite Code Pack 64-bit because development of that has been discontinued.
You could install X Codec Pack also for Windows 7 and Windows 8, but K-Lite seems to be the more popular choice with almost 247 million downloads! If you have enough space on your system, I would recommend installing the Full code pack rather than Standard or Basic. That way you can play any video file your throw at it and don’t have to worry about installing more codecs at a later point.
As for Blu-ray drives and discs, if Windows Media Player is not able to play the disc even with the codecs installed, you may have to try install something like VLC from VideoLAN. Actually, if you don’t mind installing VLC, it might be worth trying to play the disc using VLC first before installing a codec pack because VLC can play many formats without additional software. Also, make sure you have a drive that can read Blu-ray discs. Enjoy!
