We have the Tivo box that is a few years old and it is very slow in its operation with just 500gb of storage not much for HD programs, (my PC has 1 &2 TB external hard drives) plus a 1 TB internal.
Q. what is the V6? Is it better with storage for long films in HD and 4.
V6 has 1Tb.. so yes more storage but not as much as many had hoped for. (well more storage than your old boxes.. I previously had 1 TB Tivos)
