Yes, I'm basically recording 24/7, often 2 films at once. I got 118 movies off the internal 500 Gb drive, so I figured I'd probably get maybe 480 off the 2 Tb... I originally had grand plans for a huge movie collection, but if anything happens to my HR24, I guess I'm SOL! Also, if a HDD went bad, I'd lose 480 movies... Yikes - kinda risky to build a large collection this way, eh?
You simply can't trust the HRs in that respect altho they've become much more dependable. If you need to access a great number of movies, subscribe to NetFlix and just use the HRs for content you can afford to lose. Don't try to archive content unless you have a whole bunch of HRs that you can back up content on. I've got twelve active HRs and over 20TBs of recording capacity and I still subscribe to NF for the very reasons I stated above.
