...hmm:  all I can say is that I don't see anything like this with my  
clips, so I've uploaded a copy of the latest gem cvs compile to my  
website, maybe that'll work?

...unfortunately not all compressor programs make the same kind of  
file:  it's very easy to think you're compressing as one thing, only  
to have it be another...I've been bitten with this, and in practice  
have found I just need to keep fiddling with parameters in order to  
find something that works as expected in [pdp_qt]...

good luck,
jamie
