Windows 8 is finished and will soon be available for retail sale. With that in mind it seemed a good time to write an updated guide to getting codecs set up for a fully operational HTPC for both Windows 7 and 8. For this guide I’m using a new feature of HTML5 which creates expandable instructions. At the time of writing this is only supported by chrome and safari 6 but hopefully other browsers will add support in the near future.

A couple of days ago version 1.6 of Media Player Classic — Home Cinema was released. Although I don’t use MPC-HC, I do keep an eye on the releases as it can be a useful back-up when a file wont play. It’s been quite a long time since the last official release so I had a quick scan of the changelog and one thing immediately leaped at me: “VC‑1 DXVA Decoder now decodes VC‑1 interlaced material”. Until now there has been no open source x64 codec that will decode interlaced VC‑1. Finally having this available completes coverage for all the media files I have ever tried to play. Hopefully this will also get added to ffdshow tryouts and LAV Video in the near future.
I have recently been suffering corruption playing back some H.264 files with FFDShow tryouts. After a bit of experimenting I’ve found that the last build without this issue is build 3949 from 24th-July. I previously had issues with earlier releases of FFDShow that didn\‘t work with DXVA at all — fortunately build 3949 doesn’t suffer this issue. I also previously had a problem where some builds of FFDShow were less efficient on my HTPC and were unable to smoothly decode some high bitrate movies, e.g. a rip of the Inglorious Basterds Blu-Ray, which has forced me to continue to use an old build from mid-2010 until now. Build 3949 doesn’t suffer from these issues either — so in terms of the 3 problems I’ve had over the years with ffdshow, build 3949 doesn’t suffer from any of them, making it my build of choice for the foreseeable future.
DXVA in ffdshow, which was broken for the last few builds, appears to have been fixed, at least in the 3878 x64 build from 11th June.
Thanks to a guide on theHTPC.net I have been able to get subtitles working with hardware accelerated decoding in Windows Media Center 7 x64.
For this simplified guide to work you must already be comfortable with the various tweaks necessary to change the default codecs used in Media Center. Once you know how to tweak codecs (and change their merits) you can simply follow these steps…
