I tried registering the LAV filters from under Windows XP, but it was not possible. That is what I ended up doing - I thought you meant that there was a feature in the MPC-HC player to do it in bulk. In TC: select file, type 'regsrv32 ', press Ctrl+Shift+Enter, then Enter, go to the next file… mp4 files in neither graphstudionext64.exe nor graphstudionext.exe - I get the same Unknown HRESULT (0xFFFFFFFF) Notice that these are files that I can play in 'Windows Media Player', Windows 10's 'Photos' App, and 'Movie & TV' app plus other players I have. 5.01, so I will try and older version now.ĮDIT: Just tried graphstudionext64.exe v. Maybe there is an error i graphstudionext64.exe v. Under Windows 7 graphstudionext.exe shows that the files are first passed to 'MainConcept MP4 Demultiplexer' and then to the same Microsoft decoders. Under Windows 7 graphstudionext64.exe shows the same error as under Windows 10. Interestingly enough the same thing happens under Windows 7, where I can play the files in 64bit Lister with the Directshow media player. The Cyberlink stuff was preinstalled when I bought the computer in 2013. So I guess that it could be the CyberLink MPEG-4 Splitter that doesn't work in 64 bit mode. If I use graphstudionext.exe I can load the files - and they are first passed to a 'CyberLink MPEG-4 Splitter (PDVD10)' and then passed on to 'Microsoft DTV-DVD Video Decoder' and 'Microsoft DTV-DVD Audio Decoder'. Hmm, if I use graphstudionext64.exe, I cannot load those files that crash TC - I get an Unknown HRESULT (0xFFFFFFFF)

On all systems I have copied the files from to TC's filter64 directory and the files from to TC's filter32 folder - but I have not installed or registered them.īut it is reproducible with a clean. Under Windows XP (32bit) I can only play formats that the old Windows media player can play, like. All the files I have tried plays without problems in TC 64bit under Windows 7 (I have tested 2 Windows 7 machines).

mp4 files, because I know that they can be made with different codecs. mp4 file, TC simply closes down - no error message from TC or the system. avi - I have no problems with the 32bit version. Under Windows 8.1 and 10 I have problems in 64bit TC playing several file types: mp4. Until today I had only tried the new DirectShow media player on Windows 7, and here everything works fine
