I can't offer much help here.
If you have not already, use v4l2-ctl to set the PVR-350 output to the
explicit video standard before outputing data to /dev/video16.
The MSP4418 chip is responsible for generating analog audio output, once
the CX23415 decoder has decompressed the digital audio. You may want to
use v4l2-ctl --log-status /dev/video16 to see the status of the MSP4418
chip for both the good and bad audio.
You may also wish to set some debug flags when loading the msp3400 and
ivtv drivers:
# modinfo msp3400
# modprobe msp3400 debug=3
# modinfo ivtv
# modprobe ivtv debug=0x3ff
Maybe something in the logs will stand out as a difference between
playing the two type of clips.

Andy
