Crystal Acoustics has one of the smallest HD Media Player we have seen and they call it the PicoHD5.1 Pocket 1080p Media Player. It is actually smaller than the remote control that comes to operate it, it comes with a few input and outputs which includes digital audio, HDMI, SD/MMC card slot and an USB port. There is no on-board storage so I guess thats where the card slot comes in play, it also supports USB memory sticks and FAT, FAT32 or NTFS formatted external HDD drives as well. It supports the playback of various media files including MKV, DivX, MP3, FLAC, JPG and BMP images. Files can be above 4GB in size (essential for 1080p MKVs, for example). The Crystal Acoustics PicoHD5.1 media player is also capable of downmixing Dolby Digital and DTS audio soundtracks to a stereo mix, it is presently available for purchase and goes for a mere £49.99 a pop.
