[mythtv-users] Settings vs file size question

[Khanh Tran]

It depends on what you're watching a listening to this on.  I'd lower
the video bitrates by 1,500kbps on each and bring the audio down to
128kbps.  

Lowering the resolution helps too.  Each frame will be smaller, allowing
the video bit rate to be more effective in quality.
