I'm having the same symptoms on a multi-PVR-250MCE system.  I think it's 
from the splitter reducing the signal strength, but I'm still trying to 
find a good solution.  It seems the $5, 4-way splitter from a certain 
supercenter in my area is not high-quality and not recommended for cable 
TV.  Coupled with the fact that the cable feeding the house is split 
with another 4-way splitter and that the cables are using twist-on 
F-connectors, I think the signal strength is way too low by the time it 
gets to the card.
