let's take it apart...
1. Your MCI2P controller needs a brain. This could by any Windows PC which is capable to run the software provided by D-Box. In a standalone controller the MCI2P or a similar controller and a PC is put into one box, which can be controlled like a consumer electronics device. So the PC providing the brain to your controller does not necessarily have to be your HTPC.
2. Apart from the controller thing, you need a playback device for your movies which is capable to supply an unaltered Dolby Digital or DTS stream through either optical or coaxial SPDIF. This is needed by the controller for synching the motion to the movie that's playing.
Now that playback device will usually be a Blu-Ray player. As has been mentioned before there are machines that can supply the lossy digital signal for synch purposes and stream HD sound through HDMI at the same time. Alternatively a setting in which the playback device does the decoding of HD and serves it via a 7.1 analog out and still streams an unaltered lossy DD or DTS signal would also be fine. The thing that I termed "playback device" can be anything that's capable to play Blu-Rays/DVDs, stream DD/DTS, and provided the movie streaming, sound and video options you like or need.
A HTPC certainly offers the biggest choice in streaming and codec options but is currently limited by the available hardware and software in some context - and let's face it, D-Box is still a way too exclusive gimmick so that the big PC hardware manufacturer will start considering its requirements in their product development. On the other side are the Blu-Ray players which offer reliable playback of disks and some of them can do Blu-Ray 3D and might have limited video streaming options. In between are media players and hybrid media players like the Dunes. When talking about video streaming, I exclude the online video streaming options like Netflix, Amazon, Blockbuster & co., but I am talking about having a 1:1 ISO, VOB or M2TS copy (or a MKV container that houses the unaltered AV streams) of a movie stored either on a server or just an external hard disk. Whether this storage device happens to be your HTPC and if the brain for your controller is your HTPC or any other PC doesn't matter.
So you need a controller brain, a playback device and, if AV streaming is an issue, a storage device. You might be able to cover the three requirements with on machine (e.g. a HTPC), but you might be limited by its capabilities in some context, as discussed before.
Hope this helps!
P.S. Another point that has been made in this thread about devices that provide a lossy DD/DTS signal from a HDMI stream: While there are devices that are capable to encode a signal to a lossy DD/DTS, such a DD/DTS signal would most likely not meet the requirements of an unaltered DD/DTS stream as required by D-Box.
