Until 0.21 in February 2008 Bob was the best deinterlacer
available. Sadly my frontend doesn't have the CPU horsepower for the
Greedy and Yadif deinterlacers that 0.21 brought. Bob is also (aside
from Greedy/Yadif) the only 2x deinterlacer, which means
amazingly-smooth pans and movement when watching 1080i content on my
(progressive) flat panel.

Once Nvidia and MythTV's code both mature, hopefully I'll be able to
use Advanced Temporal 2x deinterlacing on my VDPAU-capable card. Until
then I am content to use One field via VDPAU as a stopgap.

Yes, the clever scheduling is a godsend. My series 1 TiVo didn't have
the equivalent of MythTVs "Find One" recording rule and resolving
conflicts with the single tuner was painful. Having multiple tuners
isn't very worthwhile, either, if such manual intervention is needed
to resolve every conflict; I'm curious on whether TiVo's scheduler's
improved since 2005.

Like you I am not wedded to MythTV. If something better comes along
I'll switch to it, although admittedly whether I could bring my
recordings along (And the metadata!) would be important. I'm not
holding my breath, though; MythTV does all I need and more.
