So there seems to be several individuals with the same issue:
1) HDPVR 1080 playback on mac-mini using 0.24 with the quartz-blit or
xv-blit profile was functional.
2) Upgrades to 0.25 has introduced a new performance bug that is
affecting all profiles available. This bug is manifests as stuttering
audio/video. Other types of 1080 encoded playback works great (ie, the
HD test video)
What can we do to help troubleshoot/fix this bug?
