Hi everyone, I'm going to get a DirectTV package with Tivo. The basic unit that's included has a 35 hr capacity. I can upgrade for a couple hundred to something like 105 hrs. At this point, it doesn't strike me as being worth it, but wanted to query the community. Is 35 hrs adequate or do people find that it can be limiting? Also, I've heard of people dropping in their own hard drives into the Tivo to increase capacity, is this difficult? Thanks, Ron.
