You didn't mention what hardware you are using, whether you are  
recording/watching HD or SD and perhaps some details of your system.

Your system may simply lack the horsepower to do what you are asking,  
if it does have the power required you could have an interrupt  
problem, a PCI latency problem, a disk system setup problem (are you  
using DMA?), problems with your video driver (nVidia 8178 using vsync?).

So some more information will make it easier to diagnose you problem,  
I infer that it was working before you rebuilt it so it is probably a  
correctable situation.
