So, I picked up a couple of used Tivo HDs in support of my move to OTA when my D* contract is up. After playing around with them for an hour, I remembered how easy Tivos were to use. Yes, the SD GUI is not nearly as pretty as the D* HD GUI, but it is clearly readable and provides very snappy performance compared to my HR24s. The THR22 does not have the nice MRV functionality, but I would give that up if I could count on the receiver to respond when I press list, guide, exit, etc. I really wish DirecTV had never abandoned Tivo back in 2005 as I loved my HR10-250 and my DVR40. After yesterday's experience, I would get the THR22 if I was signing up for DirecTV now as a new customer. If OTA does not work out for me, I may consider switching to the THR22 if I renew with D*. Maybe by then, MRV will be working, even if it is just the Tivo-style transfer of recordings.
