Testing
The O!Play HD2 played back a lot of different formats but, some seemed troublesome. For instance, when I tried to playback a FLAC file encoded at compression level 8, the O!Play HD2 had stuttered and distorted playback. And when I tried to play a video file (MP4, H.264, AAC) that I took on a Samsung handheld camcorder, the video was severely distorted. Luckily, there’s workarounds for each problem. For the FLAC issue, just encode the file at a lower compression ratio and the O!Play HD2 will play it back without a hitch. For the video from my Samsung handheld camcorder, pressing the “Display” button on the remote to bring up the video information (container, codecs, etc), then closing that display menu seemed to mysteriously solve the distorted video. Here’s a nice table with formats that were tested on the O!Play HD2:
| Video Formats | |||
| Container | Video Codec | Audio Codec | O!Play HD2 Can Play It? |
| AVI | H.264/XViD/DiVX | ADPCM/MP3/AC-3 |  |
| AVI | Uncompressed | Uncompressed |  |
| FLV* | VP6 | MP3 | |
| ISO | DVD (MPEG-2) | AC-3 | |

| MTS | H.264 | AC-3 | |

*The blue dash signifies that the O!Play HD2 can play MP4, H.264, AAC, however, as explained above, I experienced an issue playing an MP4, H.264, AAC that was recorded from my Samsung handheld camcorder. Problems weren’t consistent across all MP4 , H.264, AAC files.
