Problem:

When I load Pinnacle TVCEnter Pro CPU utilitization jumps to 97% and sometimes pins to 100%.  When I shutdown Pinnacle TVCenter Pro CPU drops to 7% 

Questions:

1. Am I using the latest version software?

2. Are there patches for this issue? 

3. Is anyone else experiencing this problem?

4. Are there any Windows XP tweaks needed?

TVCenter Pro 4.98 is the latest version for your hardware.

You can lookup Dell Supportpages more more recent drivers for your chipset and grafics card. If that won't help, try directly from the supportpages from the manufacturer (i.e. Intel, if you use an Intel chipset and ATI for your graficscard).

Maybe you use some energy saving setting which might reduce CPU speed?
