I've been running this for a few days now with no problems, that could
mean it hasn't been required or its worked fine.
I've been thinking of moving this cablebox over to my master backend
and converting the box there to record via firewire instead of through
the PVR-150. This of course will have the problem you mention of a
recording box getting reset.
Which got me thinking, this reset doesn't need to occur that often (at
least in my case), and I don't know how things will behave when I've
got both boxes daisy chained to one machine, but... What would the
effect be of reseting the bus when no firewire devices are recording
right before one will begin recording? Sort of a "lets do this just in
case" sorta thing?
