Large videos require sufficient disk space and memory.
Try closing any applications that are running to free up memory.

| Online streaming video may become choppy if you are downloading many things at the same time. Wait until your downloads complete before viewing online video streams. |
| If your video locks up at a certain point; simply play the video again and skip the area in which it locks up. |
There is software called "AVI DeFreezer" which may be capable of removing frozen portions of the video. |
