If you’ve got a system capable of handling all the resolution video you plan on throwing at it and you do need subtitles with your video playback, and most users will considering foreign dialog usually present in a few movies in everyone’s collection, we’ll need to install a subtitle renderer. To display MKV files inside the Media Center movie library you’ll also need to install one of the available registry entries for either x86 systems or 圆4 systems. Install the Gabest splitter package by extracting the files to the root C:\ drive and running the gabest_enable.cmd file as administrator (right-click -> run as administrator). To play most video files using the built-in decoders you’ll only need to install a good splitter and we suggest either Haali’s splitter or Gabest’s splitter which you can download for x86 systems here and 圆4 systems here. If subtitles aren’t a problem, however, we advocate a minimalist approach to everything here at Hack7MC and encourage using the built-in decoders since video quality across any set of decoders is unlikely to vary much if at all. Most cannot decode and display subtitles while still retaining DXVA capability. In fact this is a problem you’re likely to find across any DXVA enabled decoder. The problem with using Microsoft’s built-in decoders for playing back your video files is the almost complete lack of support for subtitles of any kind. Microsoft’s built-in decoders are perfect for DXVA acceleration and require only the installation of a good splitter to play most video file types. With modern video formats reaching enormous resolutions some older CPUs have trouble processing them without severely crippling the frame rate, the addition of a more recent video card to an aging machine can clear this up with DXVA however and save an older box from the recycling bin. The first question is do we need DXVA (hardware acceleration) or why would we need to use hardware acceleration? Hardware acceleration in the form of DXVA requires the proper hardware, a recent video card with sufficient power, and takes the load off of the CPU when decoding video files.
How do we choose which route to go while installing our Media Center setups for the first time (or after having trouble with an already setup machine)? First we’ll have to take a look at what we want from our setups.
Should you stick with the built-in Microsoft decoders or get something a little more tweak-able? Even the built-in decoders need some help playing a number of file formats available, including the most popular format among enthusiasts, MKV. Choosing the right codec setup for your Windows 7 Media Center build can be tricky.
