The Dolby Digital Orchestra demo is the outlier here. At 79 seconds and 64.5MB it’s the longest file on the page by far, and with over 28,000 downloads it’s pulled nearly five times more than Game, the least downloaded. The other four are all under 20 seconds and under 14MB — quick functional clips rather than proper demos.
One thing that catches people out with Headphone: it’s 2.0, not 5.1. Dolby designed it specifically for their Headphone processing — surround simulation through stereo headphones — so on a normal 5.1 setup you’ll only get the front two channels. The Dolby Digital Orchestra demo also stands apart on the technical side: 720×576 PAL at 25fps versus 720×480 NTSC for the other four. Most players won’t blink, but if yours struggles with mixed framerates in the same session, run Orchestra separately.
Fire and Optimizer are the smallest files here — 3.3MB and 1.96MB, 7 and 9 seconds respectively. They exist mainly to confirm Dolby Digital decoding is active, not to impress anyone. Game and Headphone are a few seconds longer and slightly more useful as actual listening checks.
All five use MPEG-PS (VOB). VLC plays them without issues. Windows Media Player in basic configurations may need the MPEG-2 codec installed separately.
