In order to resolve the Xbox 360 MKV playback issues, I highly recommend you use the WonderFox HD Video Converter Factory Pro to convert any audio/video to files supported by Xbox 360. This converter offers many digital formats and devices for output. You can convert MKV files to MP4, WMV, AVI, and other formats or devices you want with this software. In addition to helping play MKV on Xbox 360, this software can help you solve similar issues caused by incompatible formats on other devices, such as watching MP4 files on Samsung TV, playing MPEG on iPhone, etc. Other practical video & audio processing features, like editing, compressing, recording, downloading, and so forth, are also available to use.
