New description:

 After the ffmpeg resync in [20797], TrueHD and LPCM 8 channel audio tracks
 cause loud, persistent white noise.  This affects all primary audio tracks
 in HD-DVD material and many primary audio tracks from Blu ray material.

 After switching to the TrueHD track, the audio becomes loud white noise,
 and the video framerate is halved.

 30 second Sample available at:

 http://www.fecitfacta.com/truehdfail.evo

 I can provide additional samples of varying lengths on request.  Thanks!
