Ha, so order matters.  I should have tried that.  Well it playes now 
properly, only problem is video is reported as being about 3x off (and 
will horribly missync if I have autosync enabled).  After 
fast-forwarding, this is what it reports:

A:  89.5 V: 281.6 A-V:-192.160 ct: -0.100  8441/8441   0%  0%  0.0% 0 6 0

But the sound actualy matches up perfectly.

Thanks,
Peter
