We have been Provideo's US distributor since late 2004 and I've not 
heard of a PV-150 part number, and isn't not a current part number.

I figured, thanks

Okay.  You can easily access four ports on the PV-155 / PV-981, but to 
access the sub (/dev/videoX,1-3) channels you need to add the modprobe line.

painful then pulling teeth.

I think I explained that about with the sub channels, if I'm missing
