the drive i'm currently using is a 2TB that is about 70% or more full
NTFS format
it might be the number of files on the drive slows down the time it takes the PVR to initialize
I'm going to use another drive 'new or repurposed'
Bob .. by pvr function
do you mean 'time shift' function ? pausing live video
i have tested that, But for me thats not a primary function
not saying iI'll never use it, i probably will at some point
if i have to take a phone call or something
but the Hi-Def recording of live TV is my main reason for getting this unit
