The Aios had no issues playing any of the files I threw at it. Several raw camcorder m2ts files that I have trouble playing back on my own computer played flawlessly on the Aios. Although this is likely due to missing codecs on my part, the fact that the Aios can play them immediately and without work-arounds is excellent. Audio files were also played with absolute ease. FLAC files are indeed able to be decoded without issue, and I commend Pivos for choosing (and Realtek for making) the excellent RTD1185DD media processor. ISO image files were able to be played back as well and provided no difficulties. The remote control worked well, and all the buttons performed their functions admirably. Playing files from a hard drive or an external flash card saw no slow downs, skips, or any other unwanted occurrences.
