You have more examples for when things change in your configuration. :)
Besides, if you edit one of the defaults, then you may be likely to tell
someone in the future (after you forgot what you changed), "Oh, just use
CPU--," which may cause some confusion. If instead you say, "I'm using
'Custom XvMC Simple,'" then others will know you have customized your
config. Then, you can use a query like the ones at:
http://www.gossamer-threads.com/lists/mythtv/users/323894#323894 to show
them your configuration.

It can be confusing when trying to get things to work properly, but I
think the general idea of /trying/ to play things back even if
misconfigured (for the current hardware/software) isn't too bad.
