I just purchased a HD Tivo (HR10-250) from bestbuy with my $300.00 gift card. I have been reading posts about other HR10-250 owners complaining of their units locking up, or running slow. So far out of the box mine is working fine with no problems. I did notice that sometimes the unit slows down after I finnish editing my channel lists. Is my unit in time going to have problems?? Is the DTV Dvr Plus better than the HR10-250??
