I presume that you are referring to linear PCM output. The DVD Player
is client of AUHAL for linear PCM output and as such, if it didn't
work, other clients, like iTunes and QuickTime, would probably also
have issues. Do they?
iTunes and QT Player both work normally.
There are lots of new things in the HAL in Tiger, so without more
info, it's hard to say what you might be doing wrong. One thing you
can do is log the calls to your plug-in (including arguments and
return values) when things work and when they don't and look at the
differences.
Well even when tracing iTunes, QT Player and DVD Player I usually see
a lot of differences in the call sequence...
Chances are your plug-in is missing some crucial bit of
protocol.
Another symptom is the fact the video playing is completely sluttery
or event stops completely. Could this be related to timing function
not implemented correctly in the driver?
Thanks
