I do record to a software RAID, with LVM over it. Does that have the  
same effect as a hardware RAID? Or does it not matter software/hardware?

I have been recording to this drive with this card (PVR 250-MCE) for  
a while and seen no outward signs of problems. The reason I posted  
was because I seemed to be missing big chunks of recorded programs  
since the 8.1 RC (maybe on the order of a minute or so, its hard to  
tell.) Perhaps that has to do with the other errors listed?

I am applying and will restart. If you don't hear back from me, you  
can assume all went well. ;-)

Thanks!
