I have an almost identical frontend setup, 2009 Mini outputting
MiniDVI->HDMI to a 720p display, so it's not surprising that I'm
seeing the exact same issues with KGO and KTVU. Two observations:
- I notice that the playback improves (and the FE log messages
subside) if I change the focus of the mac by command-tabbing to
another app, such as the Finder. This lasts for ~10 seconds before
the problem returns
- I also noticed that the FE log error messages are the same as I see
if I try and use digital audio (speakers to "5.1" from "stereo").
However, this results in accelerated playback for all types of content
Do you know if there is a ticket open for this issue?
