Hey, it looks like the problem may be right there, extra audio buffering
is not set if the decoder is recreated but not the video output method.
For some reason this decoder setting is being set in NVP::InitVideo
instead of NVP::OpenFile where all the other decoder options are set..
It isn't the whole problem, but combined with the fix for #774
that bob.r AT plutohome.com posted this appears to fix the problem.
