Buenas, creo que MEL + FEL Dolby Vision perfil 7 sólo es posible con reproductores que tengan unidad óptica para discos físicos. Es decir, los Oppo de antaño que ya sólo se pueden conseguir de segunda mano. Imagino que el único que reproduce hoy día MEL + FEL Dolby Vision perfil 7 es el Chinoppo M9205C porque es el único que veo que tiene unidad óptica para discos físicos.

Sin embargo, he encontrado esta info en la web de Dune HD con respecto a su modelo Dune HD Max Vision 4K y me ha entrado la duda:

Playback of Dolby Vision ISO/folder structures

• The media player supports direct playback of*movie ISO/folder*structures*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 RTD1619DR-based media players do not support this. Dune HD media players are the only hybrid network media players in the world that combine*this functionality*with support for Internet video services and Android applications in one device.
Widest support for Dolby Vision file formats

• Dolby Vision is supported for all popular file formats (MKV, MP4, TS, M2TS, ISO, movie folder structure). All popular Dolby Vision profiles (P4, P5, P7 MEL and FEL, P8) are supported. The media player supports the largest number of variations of Dolby Vision file formats of any other media player.

El R_volution PlayerOne también entiendo que dice que lo reproduce:

Our media player supports direct playback of full Blu-ray disc images (BDMV and ISO) with menus in Dolby Vision (MEL and FEL)

¿Entonces Dune HD Max Vision 4K y R_volution PlayerOne reproducen MEL + FEL Dolby Vision perfil 7 o estoy entendiendo algo mal?
