If your player is skipping, your selected bandwidth might be too high for your actual Internet connection. You need to lower your bandwidth setting. On the player, in the upper left-hand section is the "Preferences" link. Clicking it will present you with the different bandwidth options available. Selecting a lower bitrate than the currently displayed bitrate will restart the video at a lower bandwidth setting. This should prevent skipping.

Streaming video over the Internet requires a great deal of bandwidth, and unfortunately connections slower than 100k connections are not fast enough to give you a dependable video experience. Your best viewing experience will occur with a DSL, cable modem, or T1 Internet connection with speeds greater than 300k.
