One processor but Device manager shows ACPI multiprocessor

[Guest]

I just noticed that the Device manager shows ACPI multiprocessor and also
shows two identical processors - Intel Pentium 4 CPU 3.00 Ghz but I only have
one. Searching for explanation of ACPI found BB on which user blamed this
setting for jerky DVD display. I have similar problem in video capture,
constant hesitation and unuseable files. Is it a big problem to change to
ACPI single and remove one of the processors in Device Manager? I'm on XP
SR2, 512 memory, Pentium 4 3.00. Thanks!

This is to correct setting for most PCs. The ACPI refers to the way the
motherboard gives out the IRQs and other resources.

The two processors are correctly set. This indicates that you have a
Hyper-Threading processor. This physical one processor provides you with two
"virtual" processor. To remove this, you need to de-activate the
Hyper-Threading feature of the processor in your PC's BIOS and re-install XP
SR2.
