I've got a HD3000 and PVR150 working flawlessly on my machine. I'm using the
DVB drivers for the HD3000 since I only care about digital channels.
I imagine running an HD3000 with a PVR500 would work as well.
Good luck getting it all working.
As well, could you respond to me off list which firewire chipset your using,
whether you compiled the required firewire libraries from source, what
versions of the libraries your using, and a guess as to your success rate in
channel changing and capturing? I'm trying to put figure out why some setups
work and some dont.
