Question 2. I have audio but don't see any video?
Most likely, you have Version 3 of QuickTime. Make sure you're using the latest version. You can download it here. Windows Media Player could also be hijacking your settings.
Sometimes closing the window with the
movie and then reloading the movie will clean up the video problems.
We've noticed several cases where simply reloading the movie clears
up the video problems.
Start > Settings > Control Panel > QuickTime > Browser
Make sure there is a "+" next to "QuickTime Movie" (.mov, qt). If there is, double click until it is gone, then double click again until it is back.
MAC USERS: Apple > Control Panels > QuickTime Settings > Browser Plug-in> Mime Settings.
Make sure "Use QuickTime Plug-in" is selected for the video and audio.
Netscape Users: In Netscape (Edit > Preferences > Navigator > Applications). There should be an entry for "QuickTime Movie" and it should be "MIME Type: video/QuickTime" and "Handled by: Plug-in"
Internet Explorer Users:
Mac Users: Go up to Edit > Preferences > Receiving Files > File Helpers. Make sure the Application QuickTime Movie is set to the MIME .mov.
Question 3. The video starts to play then stops
Check the status bar of the movie. The darker part indicates the part of the movie that has been downloaded and can be viewed. As long as the playhead (circle) is in the darker area, your movie will play fine. If it gets ahead of the darker bar, then the movie will stop playing. This means the movie hasn't downloaded enough to play.
During the download, you will be able to view the portion of the video that has downloaded, while the rest of the video continues to download from our servers.
Question 4. The audio seems a bit choppy
We have had to compress the video and audio at higher compression rates to make them accessible over slower connections.
