https://www.dune-hd.com/products/dune-hd-pro-vision-4k-solo#key-featuresPlayback of Dolby Vision Blu-ray images The media player supports direct playback of full Blu-ray images (BMDV and ISO) in Dolby Vision format (MEL and FEL). The extended Dolby Vision information is used and transmitted to the TV to improve the picture quality. This is possible due to the unique video playback and output engine created by Dune HD. Other RTD1619-based media players do not use Dolby Vision information when playing Blu-ray images. Dune HD media players are the only hybrid network media players in the world that combine support for Dolby Vision Blu-ray images with support for Internet video services and Android applications in one device.说是只有Dune HD Pro Vision 4K Solo支持DV，价格449刀感觉有点意思，这里明确提到支持Proifle7 FEL了，按照Dune的开发能力，支持MKV格式的Profile7 FEL应该不难
