Okay im pretty sure there is something wrong with the current firmware and
my pvr350.. can't find instructions on how to get the older firmware
versions.. Any help would be appreciated.. When i do the dd if=/dev/video0
of=/dev/video16 bs=64k test i get choppy output that hangs after about 10
seconds and no audio.. Now all this is doing is pumping video/audio right
out of the encoder and directly into the decoder which should be seemless
and was before i rebuilt my box.  So im pretty sure that my problems lays
in the firmware for the pvr350 im using.
