[mythtv] MacOS X binary

[Jeremiah Morris]

It's great to see all these OS X users here!  Thanks for all your 
effort, Janne!

As one of the OS X porters, I just wanted to respond to some of the 
current limitations of the port:

- I have prepared a video patch that fixes the resizing problems, 
honors window vs. fullscreen mode, and is less CPU intensive.  It's not 
yet in CVS or in Jan's build, but I hope to get it into CVS soon after 
squashing a few intermittent bugs and adding preferences for some 
Mac-specific features.

- As mentioned above, CPU improvements are coming soon.  It's still 
pretty intensive, but initial tests by Nigel Pearson indicate that most 
of the optimization will probably be done in FFmpeg (the library used 
by MythTV to decode video), rather than Myth proper.

- Interlacing has not been examined, so I don't even know where to 
start yet.  Once video is playing at a decent rate for everyone, then 
we'll add on the deinterlacing.

- Live TV is worse than watching a recording, even if you have a fast 
connection to the backend.  Elsewhere on this list, lowering the MTU 
was suggested as a possible solution; if it works for me, I'll report 
back with detailed instructions.


With all this interest, the Mac build should continue to get better and 
better. Thanks again,

Jeremiah
