Brian, in addition to the technical challenges regarding the need for
MythTV to first move away from writing directly to the database that
others have mentioned, also consider that your examples all have a
much, much, much larger installed base than MythTV does.

If MythTV were used by tens of millions of users and embedded devices
around the world, I am sure that backwards compability--to not have to
force everyone/thing to upgrade each time--would be a very high
priority for the developers. In addition, the developer base would be
much larger and less centralized, with the likes of IBM, Red Hat, HP,
and Oracle (to name four of the largest contributors of code to the
Linux kernel) and/or Motorola, Sony, Google, and Apple all working on
improvements.

The MythTV community, however, is much smaller in both breadth and
depth, and its users can be depended on to upgrade with each release;
or, if they don't, they have consciously made this decision, and their
self-contained setups don't interact with other MythTV systems. Thus,
backwards compability currently isn't nearly the priority for the
developers that you believe it should be, and it's an understandable
view. Will that change? I'm sure eventually, but not now.
