2Full 7MC codec setup

I’ve pre­vi­ously pos­ted sev­er­al times about codec issues on 7mc, but I’ve now got a solu­tion that is com­pre­hens­ive, fairly simple and works con­sist­ently. With a few free codecs and util­it­ies you can have full decod­ing sup­port, DXVA, sub­titles and fant­ast­ic flex­ib­il­ity work­ing in 64bit (or 32bit) Media Cen­ter. The fol­low­ing instruc­tions are spe­cif­ic to the x64 edi­tion, but should work just as well on the 32bit edition.
1. Down­load and install ffdshow

• Down­load ffd­show 32bit
• Down­load ffd­show 64bit
• Install both

2. Con­fig­ure ffd­show settings

• Tweak any ffd­show set­tings you want — remem­ber to do it for both x32 and x64 ver­sions — e.g. I use the “mix­er” to out­put ste­reo music to my sub­woof­er as well as the main speak­ers. I also enable lots of addi­tion­al codecs in the video configuration
• Open DXVA Video decoder configuration
• Click on hard­ware accel­er­a­tion in the menu on the left
• Tick H264 and VC1
• Set “post pro­cessing” to “Sur­face overlay”
• Click on sub­titles in the menu on the left
• Tick the box at the top
• Repeat for the x64 DXVA Video decoder configuration

3. Now dis­able the in-built Microsoft Medi­aFound­a­tion codecs (note: this does­n’t break live TV) and replace them with ffdshow

• down­load the win7dsfiltertweaker
• Run the fil­ter tweaker
• on the first page, select ffd­show (DXVA) where pos­sible, and plain ffd­show for all oth­ers where pos­sible, for both 32bit and 64bit.
• Click apply and ok any warnings
• on the next page tick all the boxes to dis­able MF and click apply
• on the 3^rd page tick the bot­tom 2 boxes (dis­able MF and dis­able MF 64bit) and click apply.
• OK the exit
• Open reged­it and browse to [HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindowsCurrentVersionMedia CenterDecoder]
• Delete any entries that are present

4. Now install the required splitters

• Down­load Haali Media splitter
• Down­load the MPC-HC stan­dalone codecs in both x64 and x32
• Install Haali and enable MPEG-TS
• Extract the MPC-HC codecs
• On x64 sys­tems copy the x64 split­ter files to system32 and the x32 files to the syswow64 folder. on x32 sys­tems just copy the x32 files to system32.
• The split­ter files to copy are as fol­lows: AviSplitter.ax, FLVS­plit­ter, MatroskaS­plit­ter, MP4Splitter, MpegSplitter.
• There are oth­er split­ter files which you can also copy and register (see below) but I haven’t needed them
• Register the split­ter files as fol­lows: open an elev­ated com­mand prompt, for each file you copied run the com­mand “regsvr32 file­name”. If you are on x64 win­dows change dir­ect­ory from system32 to syswow64 and repeat the registering

5. Use registry tweaks to use the MPC-HC split­ter for most files and Haali for .mkv and .m2t files

• Open reged­it and browse to [HKEY_CLASSES_ROOTMedia TypeExtensions]
• Check that their are keys for .m2ts, .ts, .mp4, .mkv, .m2t and cre­ate any new keys that are required
• Inside each key check that their is a string with the name “Source Filter”
• Set the value of source fil­ter for .m2ts, .ts and .mp4 to {1365BE7A-C86A-473C-9A41-C0A6E82C9FA3}
• Set the value of source fil­ter for .mkv and .m2t to {55DA30FC-F16B-49FC-BAA5-AE59FC65F82D}

6. Enable ogg and flac audio

• Down­load the xiph ogg­co­decs for both x32 and x64
• Install both
• Down­load WMPTag­Plus — oth­er tag extenders don’t seem to work so well
• Dis­able the x64 Media Play­er by renam­ing the folder “Win­dows Media Play­er” inside the Pro­gram Files folder (on x64 win­dows only!) and then cre­ate a new “Win­dows Media Play­er” folder. copy the con­tents of the “Win­dows Media Play­er” folder from the “Pro­gram Files (x86)” to your new folder. This forces Media Cen­ter to use the Media Play­er 32bit engine for music — which sup­ports the tag extender. Once a 64bit tag extender is avail­able this will no longer be necessary

7. Reboot and you’re good to go.
Any .m2ts files that don’t play back prop­erly rename the exten­sion to .m2t (which as far as win­dows is con­cerned is the same).  This will change the split­ter used and should resolve any play­back problems.
