[mythtv] RE: No video in OS X frontend

[Michael Sherman]

As a follow-up, I've solved this no-video issue with OS X Tiger.  If  
anyone else has this issue, I'll just note this for the archives.   
The error is caused by new png libraries provided by the new 10.4  
Tiger release.  If you have 10.4, you need to get rid of the libpng  
libraries you may have compiled and installed into /usr/local/lib/.   
Just remove those and it'll use the new system default libs, and  
it'll work just fine.
