True, but very problematic on E2 atm especially with newer kernels. TBS is completely indifferent to providing better open source drivers to fix various issues such as the I/O errors, the signal missing STB freezing, the faster zapping, the CPU consumption and more. When the SDG team first implemented MIS support for TBS5925 on OSmini last February, while on kernel 4.2 and 4.3 the problems were not (so) severe (see my videos from back then). With every kernel update things get worse and worse, there's no way you will not see spinners and delay. Even skins cannot load fast while zapping. STBs with older kernels seem to benefit more, but generally the whole experience is far from seamless right now and it's very disappointing how the whole thing turned out. Luckily internal MIS decoding will solve all these issues for good, and it's a good thing the code was at least patched on the E2 core, just to make support for newer internal tuners a lot easier.
I heard that the Skystar USB HD card (the one without CI) is now the best solution for USB MIS, the driver support is far superior and the function is way lighter. The problem is that these cards are nowhere to be found right now...
