"plays what MythTV generates" seems terribly obvious actually.
If it can't play recordings, how can you call it a MythTV device?

Not really. Linux is not a closed platform. That means that 3rd parties
are free to do interesting things like VDPAU and ffmpeg.

A Windows PC isn't a closed system either. Nor is a Mac.
Either one of these can use ffmpeg or VLC to good effect. You won't have
to worry about whether not not you can install any of that stuff on a Mac or
a PC. You don't have to worry about any of that being disallowed.

Weak CPU. It's the same reason the AppleTV or Mini9 doesn't make a very
good frontend if you've got HD h264 recordings. Although the ARM is even
weaker than an Atom. Software playback on iDevices is gruesome.

In a very limited way. It's very misleading to claim that the iPad
can do h264.

That does not alter what can or cannot play back something.

Fine. Go ahead. You seem to be the one with an axe to grind.
