Is anyone finding their 750GB drive not to be big enough? If so, what are your viewing habits like? I've only been using mine since mid-September. I've had two HD-TiVo's, one with 63 HD hours and one with 70 hours, for the past couple of years. I generally had the same season pass list on both, but in reverse order on one of them, to make sure I didn't miss anything when I had 3-or-more-way conflicts. We're usually several weeks behind on shows, and it generally gets worse as the TV season goes on. We catch up a little during heavy rerun periods but get further behind during sweeps. We could usually enjoy the convenience of watching shows in either room for a few months, but then eventually we have to go through and delete duplicates from one or the other, and usually lose a few recordings if we don't realize in time that we need to do that. I'm hoping I won't have to deal with that as much with the 750GB drives and a lot more mpeg-4 recordings. Plus the space remaining indicator will at least let me know when I need to delete stuff. But I've also gotten rid of my SD-TiVo so my kids will be recording a lot of shows on the HR-20 in that room. Plus with all the new HD channels I might end up recording stuff in HD that was only available in SD before. Anyway, just wondering if people are really filling up their 1TB and larger drives and arrays. I'm getting another HR20 delivered and "installed" next week and I'd like to start fresh with the external drive. I ordered a 750GB FAP from Best Buy but still have time to get something larger.
