[mythtv-users] I must be cursed with stuttering problems

[nate s]

ALSA 1.0.6 bad?  this is the first I've heard of this, and I too have
had stuttering problems.  Can you post a link to more info?  Also, for
downgrading, is it just alsa-lib or do you need to patch the kernel?

Even though I had stutter issues on ATSC content with the older nVidia card I could hit "p"ause during playback and it would go away after un-pausing.  I can no longer get it to stop stuttering even after pausing.
