I had this problem on my similar Fedora Core 4 system. Removing the 
nvidia drivers and installing the version recommended in the wiki  
(1.0.8756) cleared this up and now i can fast forward up to 120x. I am 
using  ivtv version 0.7.0 which is pretty current for my kernel.  I am  
not using any fancy video options, such as  XvMC. However the XvMC wiki 
page has info about nvidia drivers.

          As of 2006-04-7, the currently recommended driver version is: 
*1.0.8756* as it fixes the OpenGL Vsync

issues present in earlier versions, as well as fixing the AGP + XvMC 
issues on 6200 series cards.
