I've been trying to find an answer to what the use only first cpu option means and have been unable to do so. The reason I'm asking is I have a Nexus-s v 2.2 that I use in the hard mode. I have both ProgDVB versions 4.62.6 and 4.82 installed. Every so often the computer will freeze for some reason with the CPU pegged at 100%. I have 1G of DDR Turbo RAM and an AMD sempron 2600+ cpu in an XP OS computer. What should this option be set at in my case, and why? Thanks.

This option is for Hyperthreading CPU´s (Intel)
