First you must meet the requirements for WMP11. This means that you must either be running Windows XP or Windows Vista. If you are running an older form of Windows you are out of luck. I would try either Tversity or Twonkymedia at this point. So if you can meet the requirements, you need to download the WMP11 installer
After the verification process completes, go head and install the program. When you finish the installing process open up WMP11. You will have a window open up similar to this.Configuring
Now it is time to configure the sharing. Navigate to Tools > Options. You should have a window come up. Now navigate to the Library tab. You will see an option to Configure Sharing. Click on that box.
Another window is going to pop up. Click the little box to Share my media. Now you should see an Unknown Device pop up in that same windows. This is WMP11 seeing your PS3.
Select the Unknown Device and then select the Allow button. You have just now set up part 1 of the sharing portion for WMP11. Click OK.
While the Options window is still open. Select the Monitor Folders button. You will then have to add your media accordingly. Here is how I have it set up. You can do it however you like though.
Once you select OK, WMP11 will then begin scanning the directories for media. This can take a while depending on how much you are attempting to share.
Pat yourself on the back. You just finally set up WMP11 to share all your media. But let's make sure that our media is being shared. Go back to the WMP11 default screen. You will then have to click to the little tab to the right of the media icon like below.
You will have to verify for each media type to ensure that WMP11 is sharing the files. But here is how you now that videos are able to be shared. This is just a sample showing that I have video being shared through WMP11.PICTURE 6Enable H.264-MP4/M4V/M4A previews in WMP11
This registry patch will tie MP4/M4V/M4A files into Windows Media Player [WMP11] and Windows Media Center [WMC] allowing them to play this file type but also stream from WMP11 these file types to the Playstation 3 and Xbox 360 However there are caveats as it is not possible to tie a third party codec 100% into WMP without developing some sort of plug-in. Also available are patches for Flac, M2TS and MKV/MKA. I have moved M2TS off into it's own entry to keep it separate if you are looking for it click that M2TS link.
This process is compatible with 32/64-bit Windows XP/Vista with WMP11 present, Windows Home Server if WMP11 is installed should work as well. I would recommend though it is not necessary that you create a system restore point before applying these just so you have a point to return too.
Step 1: If running 32-bit Windows download this MP4/M4V/M4A registry patch.
If running 64-bit Windows (see FAQ entry) download this MP4/M4V/M4A x64 registry patch. The 64-bit registry patch includes the keys for 32-bit compatibility.
Step 2: Uninstall any codec packs or prior installs of ffdshow and Haali media splitter.
Step 3: Download ffdshow tryouts & Haali Media Splitter then install both. Alternatively if you wish to have thumbnails for MP4's in the PS3 XMB or Windows Media Center then see thumbnail entry in FAQ below.
Step 4: Double click on the registry patch to apply and it will make the changes to add MP4/M4V/M4A support to WMP11.
Step 5: Reboot your computer (don't skip this).
Step 6: Now start WMP11 and if all goes well you should see any MP4/M4V files that are in monitored folders appear in the video library & M4A in the audio library, now enable file sharing and you should be able to stream the audio & video to the Playstation 3 or Xbox 360.
That's all there is to it, if you are still having problems see trouble shooting section at the end of this page also there is a FAQ a little further below which I strongly recommend reading.
Finally check out my H.264 video encoding guide for the Xbox 360/Playstation 3 as it will generate a compatible H.264 video & it covers pretty much all you need to know plus the limitations peculiar to each console though I primarily focus on cross compatibility in the guide. Also Windows media center extenders have the same H.264 profile as the Xbox 360.
* MP4 = H.264/AAC & is playable on both the Playstation 3 & Xbox 360.
* M2TS = H.264/AC3 & is playable only on the Playstation 3 (Read more about M2TS at this link).
* M4V = H.264/AAC & is playable on the Xbox 360, to play M4V files on the PS3 you must rename the file type from .M4V to .MP4 on your PC and only then will it play on the PS3.
* M4A = AAC audio & is playable on both the Playstation 3 & Xbox 360 (X360 only supports AAC LC).
