On the TiVo Community Forum There is a posting that D* isn't supporting the THR22 anymore and they don't has spares to replace failed units. That makes the THR22 a very short lived platform. I know that this is wishfull thinking, but wouldn't it be nice if they were migrateing the TiVo software to a later box?....not! The good thing about the THR22 is that if the hard drive fails, it is a no brainer to install a new drive and get it back up and running, don't have to load an opperating system of configure the drive at all, the box does all the work. Now, if someone could hack the drive so it could be copyed to a larger drive and maintain the recordings, one could make a backup drive so you wouldn't loose your recordings. When the HR10-250 came out, Hackers were quick to jump on it and devlope software to do just that. I find it interesting that the hacking community never tried to develop any software to copy and expand the drive. Too bad.
