If YouTube videos often freeze or stop to buffer when you’re watching them, you need a tool like SpeedBit Video Accelerator.
This application was developed by the same people who made the download manager Download Accelerator Plus. Basically, it’s designed to help keep videos from buffering and images from freezing.
SpeedBit Video Accelerator remains hidden in the taskbar. Then, when it detects a video hosted on YouTube being loaded, it gets to work.
It also works with any videos that are hosted on YouTube but embedded on other sites.
In addition, SpeedBit Video Accelerator includes a small search engine that you can access by double-clicking on its icon in the taskbar.
