Hi Don,
I just tested RC4 and noticed that the delay is incorrect for my MPEG2 -captures. The delay reported for the original clip was -124ms, in earlier versions it's -44ms. The delay for the cut sample file (see below) is -80ms but it's still way off.
I'd say the delay should be closer to zero for both clips although it's hard to determine. Nevertheless, -124ms and -80ms sound off to my ears, the audio runs too early.
I uploaded a sample clip to my webspace as I couldn't log on to your FTP site.
