So I found out the application (iMovie HD version 6.0.3) that was
causing some problems:
- If I set mData be set to NULL *and* mDataByteSize to 0 for a
disabled stream then iTunes does not work
- if I set mData be set to NULL only and not changing mDataByteSize
then iMovie is crashing.
It appears that mData has to be set to NULL *only* (not changing
mDataByteSize) for streams where the IOProcStreamUsage property is
actually used, otherwise (IOProcStreamUsage not used) then the mData
has to be set to NULL *and* mDataByteSize set to 0.
Does this makes sense?
Thanks
Stephane Letz
