However Raspberry pi can manage mvc files in 3d, and it has no problems with samba shares, but it can't manage audio hd formats (DTS HD, TRUEHD...)

The Pi 2 has enough CPU power to losslessly decode DTS-HD MA/HRA and Dolby True HD to 5.1 or 7.1 PCM and can output 5.1/7.1 PCM at 48kHz 24 bit and 96kHz 24 bit. It is limited to 4.0 output of 192kHz content - but there are only a handful of multichannel 192kHz releases. Apart from Dolby Atmos/DTS:x stuff (which needs to be bitstreamed), or a situation where you need AVR processing, the Pi 2 handles HD Audio in pretty much an identical way to the audio decoder in your AVR.

So although the Pi 2 can't bitstream HD Audio, all that means is that the lossless decoding process is handled in the Pi 2 not the AVR/Amp (the HD Audio has to be decoded to PCM somewhere in the chain). So the quality, in many cases, will be identical. This is the same situation as HD Audio played on a first generation PS3 or when connecting a Blu-ray player to an early HDMI Audio amp that only coped with PCM audio and didn't include DTS HD/Dolby True HD decoding.

The Pi 2 also has no problems with other HD Audio formats like FLAC, PCM, WAV etc.

So I don't think it is correct to say that the Pi 2 can't 'manage audio HD formats'. The work done by the Kodi developers in integrating DTS HD decoding (Dolby True HD has been there for a while) will also be available for other platforms - like the Windows situations where you get 7.1PCM output but no HD Audio bitstreaming (Baytrail and Cherry Trail SoCs appear to often have this limitation)
