Which split-network-architecture, multiple tuner DVR are you going to
compare it to?

Make sure it's a DVR that does not use a fixed size ringbuffer (where you'll
lose the ability to rewind to start of play if you're watching an all day
cricket match), and that it does not dump that ringbuffer when you change

Also make sure that, of all the simple things, you don't have to "rewind" to
the beginning of a show in order to "record" a show you were watching on
livetv (which rules out all of the topfields I use).

Finally, it should be able to save livetv you watched YESTERDAY.  I'll often
flip to the news, watch it, and then flip off.  Sometimes I'll hear about
something the next day, and want to go back and view the liveTV I'd watched
the day before.

I don't know of any on the market that support any of these options, which
has been explained to you many times as the root cause of the live channel
change slowness due to its robustness, but if you do find one let us know!
