I think he means accelerated playback of video... if you have a device with XVideo/Xv support, then it should work fine in any supported players. (mplayer/vlc.. xine/ogle.. etc)
If you get verbose output from: % xvinfo You're probably set to watch a video... ![]() |

Damien: That sounds like the 24fps/25fps issue.
Outside of the US, the standard for video (with few exceptions) is 25 frames per second. (US uses a hair under 30fps). Movies are universally filmed at 24 fps. This is generally dealt with by simply playing the movie at 25 fps, which is a 4% increase in speed. A 100 minute movie now shows in 96 minutes. The pitch shift is only noticeable (to most people) when doing a side-by-side comparison. Today, most studios do a pitch transformation on the audio, so even that is not an issue. (The alternative, that is, repeating every 24th frame, would produce a noticeable jitter.)

What model Dell Optiplex do you have? Mine has worked perfectly.

The video you are seeing could be incorrectly labeled as 25fps, and your video playing software is honoring that label. You can override that label by directly specifying the frame rate (in mplayer, at least: It would help us greatly if you'd tell us what player you are using, and some little clue as to what the video is!) Or you could be comparing it to playing it on a DVD player and TV. The computer may be playing it at the correct 24fps, but the TV playing it at 25. Video is not simple! Just wait until you try to get your head around interlacing! and colour spaces, too!
