Upgrade FFMPEG in PyTivoX?

Hello,

Is there a way to insert a new version of FFMPEG into a working installation of PyTivoX? Everything works fine but the resolution isn't great. I like to be able to launch the Mac app rather than deal with terminal windows. Recent Mac OS killed PyTivo but I got PyTivoX to work.

Also, when I launch PyTivoX I get asked if I want allow or deny python? Can I just set it to "yes" and avoid the prompt?

Thanks,

Doug
