I took the easy way out and left the DirecTivo SD unit to my wife, she really doesn't care as much about picture quality as she does reliability. Typical female perspective for more things than just HD
I look at it as a chance to get my own PVR. She has filled the DirecTivo up to about 95% capacity with Dr. Phil, Oprah, and cooking shows. She won't delete the Dr. Phil episodes because she thinks the parenting advice will be handy as the kids get older. Whenever I try to set up a recording it says there is not enough space and I have to spend 10 minutes trying to find something to delete (Dr. Phil is off limits, although I have snuck a couple of deletes in there when my Battlestar Gallactica was threatened ).
So her plan is to store the Tivo up with old episodes for 5 to 10 years and be constantly having to make space for new recordings

I got her a DVD-R to archive the stuff but the thought of making 100 hours of recordings real-time doesn't sound too fun and with two small children we really don't have the time for this undertaking. I had thought about hacking the Tivo so I could archive the recordings using the PC, but it would not help for already recorded shows.
Now, she can deal with the full hard drive herself and I can have a HR20 with complete control what is recorded on it.
Eventually, when the HR20 becomes stable, I'll replace her Tivo with another HR20. Believe or not, she actually prefers the HR20 to the Tivo, except for the lack of auto-correction when FF through commercials. When she gets her own HR20, I'll probaby set up a 750GB eSata for her and she can store a decade's worth of Dr. Phils on it if she wants. I just hope Dr. Phil and Oprah never go HD, the 750GB won't be enough then :nono2:
