[mythtv-users] DTS Passthrough choppy/laggy with trunk

I am using trunk(25907) and when I play a video in mythvideo with DTS I run
into an issues.  My setup is set to ALSA:iec857:CARD=intel,DEV=0 for audio
output device  with DD and DTS checked and speaker config on 5.1 without
upconverting checked.     Playing normal media is fine but when playing
something with DTS while the receiver is showing DTS received the audio is
very choppy (multiple times a second I would say).  Playing through mplayer
with -afm hwac3 has the DTS audio working just fine.

Playback without DTS enabled also works fine.

Any help would be greatly useful.    CPU is around 5% during playback (also
using VDPAU).
