I was beginning to think a little while back what all of this hard drive space would be used for when they start becoming much larger than they are now, such as 500 hours or 1,000 hours in which nobody would need that much space for recording shows to view later.
I could see all this space being used for certain channels where you would pick the shows you want to view instantly without having to program a timer and wait for the show to air, it would already be there. They could even make it to where you could view all the shows that you watched for the whole week, month, or year, then once all of the space is used up it would just record over that data from the beginning again.
They could even make certain channels have the feature to where you could go back in time and watch anything that was on the past day, week, month, and so on if the hard drive space was great enough, perhaps channels of your choice.
They could make extra tuners work in this way and have new ways of doing this in the future than what we could even think of. This could be what the future of DVR could be like.
