[mythtv-users] Apple TV almost working. Only a slight issue remains

[Michael Brancato]

Well, I never quite figured out what was causing the audio buffer 
underruns.  But I'm closer to solving the problem.

I switched away from XvMC to XV and things became much better.  I have 
both HD and SD working in a usable state with no stuttering or jitter. 
The problem is that I can't enable deinterlacing.

With XV, my memory usage goes well above the physical amount on the 
AppleTV, and CPU is bad.  But The end result is better than with XvMC 
which uses much less CPU and loads less memory.  I'm trying to eliminate 
running processes to save memory, But I'm probably only using less than 
10MB of RAM excluding MythTV related processes (X, openbox, 
mythfrontend, etc), so there isn't much more I can save.  Mythfrontend 
seems to use over 160MB in memory itself with HD content.  I'm afraid 
the lack is ram is what is preventing me from enabling deinterlacing.

What is the cheapest deinterlacer to run with XV, and does anyone know 
why XvMC would be worse?  XvMC uses less memory and CPU, but causes 
audio buffer underruns.
