I am building a HTPC and have an HP expresscard tv tuner, which is essentially a Hauppage WinTV-HVR-1500. I figured
I may as well use it with the HTPC if I can, but I can not seem to find any specific info on whether this Expresscard runs off
the USB or Pci-x bus, as based on the Expresscard standard, a device can be designed to use one or (unless I am mistaken) both. Expresscard adapters which plug into USB slots are much less expensive than adapters to interface with the Pci-x bus,
so I wanted to figure out which bus this tv tuner runs on before wasting money on an adapter which won't work.
It appears to be an expresscard interface, which is for laptops. I suppose you could figure out a way to install an expresscard interface into your HTPC but why bother?
Just pick up a tuner card, they aren't that expensive. I've seen some USB tuners that do pretty good for under $50, but it depends on what features you'd like.
Thanks for the reply.
There are actually fairly cheap Expresscard to USB adapters, but more expensive Expresscard to Pci-x
ones. Based on the way the manufacturer built the card it can use the USB or Pci-x bus for data
routing, but I can't find info on which bus Hauppage made this card use. Your suggestion is a
good one, but if this card uses the USB bus, the adapters are actually cheap enough that I would rather
get one than buy a new tuner. When I called Hauppage, the tech support guy didn't seem aware that
the ExpressCard standard provides for data routing to either bus, as I didn't know before I researched
this, so he seemed confused, and was not of much help.
