Hey GS. The stuttering videos. Check your Start > Right-Click on My Computer > choose Properties > the Hardware tab > the Device Manager button
Check for an IDE/Atapi Controller. If you only have one hard drive and one or no ROM drive (CD-ROM, DVD), and each of these only use One IDE Ribbon, then under the Controller tree, check both the IDE Primary Channel and the IDE Secondary Channel.
If you only have one Device on each and the menu display a "Device 1", then set Device 1 to NONE. This setting will disable the Device 1 slot on the Controller.
If you have a Device connected as Device 1, then this will Disable that drive, so choose wisely.
Disabling Device 1 when it is Not in Use (!) cuts down on the search time that Windows XP uses to find available devices (disks) to write data to, including video data. Else, when an empty Device slot is enabled, Windows assumes there is a Device and tries to write to it, then finds no Device present and then looks around again. With video data on disk, less foo is best practice.
And if you set IDE Primary Channel Device 0 to NONE, then in most cases you have just disabled your OS Drive. But XP usually greys that option out so you don't make that mistake.

And if you have TWO INTERNAL HARD DRIVES, The Main OS Drive on the IDE Primary Channel and the other On IDE SECONDARY CHANNEL with the correct Master/Slave Jumper setting on Each Drive (Very Important!), then you can try Installing your browser to The Second Drive that Does Not Contain the OS. (very important!).
This is because the OS drive is still running tasks in the background.
Putting the browser or program on Drive Two (Use Only Internal Drives on separate IDE Ribbons with Duel IDE Enabled and set all Devices Not in USE ON THE IDE RIBBONS to NONE. Not for use with an external USB disk or Flash Drive. very important...) puts the program on a separate data channel from the channel in use by the OS (XP). This will speed up data access for the program.
It also works Very Well for Visual Pinball and VPinMame when they are installed to the second non-OS internal drive when lower end systems use the drives for Virtual Memory.
