There were two major questions that came from readers after we published our comprehensive Windows 8 review, and we want to expound on what you get with the Media Center/Pro packs regarding media playback, and Windows 8 and RT app compatibility.
Windows 8 Media Center And Blu-ray
Our Windows 8 review (The Definitive Windows 8 Review And User Guide), like many other publications that got their information from Microsoft, originally reported that the Media Center and Pro Pack contain codecs for both DVD and Blu-ray movie playback. This is false. They only facilitate DVD playback, not Blu-ray.
The quote most sites are referencing comes from Microsoft's blog. And, like most of the official Windows 8 pre-release literature, it contains ambiguous language regarding what's actually included in Windows 8:
Windows Media Player will continue to be available in all editions, but without DVD playback support. For optical discs playback on new Windows 8 devices, we are going to rely on the many quality solutions on the market, which provide great experiences for both DVD and Blu-ray.
Further down, in the same blog post, are the actual contents of the Media Center and Pro Pack:
...Media Center, including DVD playback (in Media Center, not in Media Player), broadcast TV recording and playback (DBV-T/S, ISDB-S/T, DMBH, and ATSC), and VOB file playback.
Again, the Media Center Pack does not include codecs for Blu-ray playback.
Alas, it's still not quite that simple.
You see, the Media Center Pack adds DVD playback only in Windows Media Center. DVDs still won't work in Windows Media Player or the ?metro? Video app. What's more, the DVD codecs included in Windows Vista and 7 do not transfer when upgrading to Windows 8 Pro. So, even if you upgrade to Windows 8 from a version of Windows that does include codecs for DVD playback, you still need one of the additional packs in order to watch your DVD movies.
We definitely urge everyone who upgraded to Windows 8 Pro this week to pick up a code for the Media Center Pack while it's still free. After January 31st 2013, the Media Center Pack will cost roughly $10. You can request a code for the Media Center Pack here. For now, it appears that you can request a free Media Center Pack code even if you have not yet purchased the Windows 8 Pro upgrade.
If your new Windows 8 PC happens to play Blu-ray discs without one of the additional packs, the OEM is most likely providing third-party Blu-ray software preinstalled.
Special thanks to Kelt Reeves, president of boutique system builder Falcon Northwest, for running the different permutations and helping us straighten all of this out.
Apps For Windows 8 And Windows RT
There was another point from our Windows 8 review that prompted a few comments. It is on the conclusion page, where we state:
Windows RT apps won't run on Windows 8 unless they're ported to Windows 8. And legacy Windows software won't run on anything except Windows 8. In fact, you can have a copy of an app in Windows 8 and be forced to buy it a second time for your Windows RT-based devices.
The first sentence isn't entirely true. Only some Windows RT apps need to be ported to Windows 8, and vice versa.
Apps written in .NET that do not rely on any native code are platform-agnostic. In other words, they are able to freely move between CPU architectures (incidentally, that's the reason why we include .NET performance in stories like AMD FX-8350 Review: Does Piledriver Fix Bulldozer's Flaws?; .NET performance is indicative of a different breed of software). Therefore, .NET-based apps will run on both Windows 8 or Windows RT. However, apps written in C++, as well as apps that require an existing code base or libraries, need to be compiled separately for both the x86 and ARM architectures.
So, will ?metro? apps work on Windows 8 and Windows RT, or not? Unfortunately, this one isn't so simple either. Why would it be, right?
Developing ?metro? apps in .NET is clearly the preferred path moving forward, as it allows the app to run on both Windows 8 and Windows RT, although creating native Windows RT apps is also an option. This is similar to how Android developers are encouraged to use the SDK to program in Java, yet also have the NDK at their disposal should they need to run any native code.
Moving on to the second sentence of our quote:
And legacy Windows software won't run on anything except Windows 8.
This part is completely true. But once again, there is a bit more to it.
Not only will none of your traditional Windows applications run on the Windows RT Desktop, but only Microsoft applications will run on the Windows RT Desktop. No third-party apps allowed. No Chrome, no Firefox, no VLC, no WinAmp. Nothing that doesn't come from Microsoft, period.
Special thanks to Adrian Silasi of SiSoftware, developers of the Sandra benchmark, for helping us break this situation down.
Finally, let's address the last sentence:
In fact, you can have a copy of an app in Windows 8 and be forced to buy it a second time for your Windows RT-based devices.
This part requires that we set the record straight. Even though some applications require that developers spend extra time compiling for separate CPU architectures, fortunately, you don't have to worry about that. Purchasing a title under Windows 8 means that you also gain access to the Windows RT version, should one exist (and vice versa). While we could not confirm this first-hand, and Microsoft is as cagey as usual in its official literature, we did confirm it with two Microsoft Store Answer Desk Techs.
So, if you were to buy an app like Angry Birds Space from the Windows Store on your laptop (x86), you're still able to download it on your Surface (ARM) without being charged again, provided you're using the same Microsoft account on both units.
