[mythtv-users] Hardware configuration and capabilities of MythTV

Thanks Rob. I checked out the HDPVR. Only problem with it, besides having to keep the cable company's DVR, is that it wouldn't make very good use of both tuners in the DVR.
Supposedly there is a new product on the horizon called the HDHomeRun "Prime" from Silicondust. Anyone know how long until this product will be available? Will it be supported by MythTV? It is supposed to have three tuners and will accept a cablecard.
So, basically, it looks like the hardest thing will be to get a cablecard tuner hooked up to make use of both (or all three) tuners. I signed up on a mailing list at Silicondust's website so I will get notification when the new product is available.
This MythTV thing will be ultra-cool when I can watch/record more than two different HD cable channels from any room in the house.
It would be no big deal to install a 1Gb switch in front of my existing router so that I can get 1Gb to all the rooms in the house.
I guess I'll have to play with the software on my existing hardware to see if I can find anything else to ask questions about. I have an old machine with an ATI All-In-Wonder card that I can play with.

Look into the Happauge HDPVR. It's the only option that will allow you
to get all your channels in HD. You'll need a cable box per HDPVR, but
it works great.

Yes, myth understands how to do this.

Typically very little. It's mostly IO. Commercial flagging and other
jobs will be the ones that use the CPU on the backend, and playback on
the frontend requires CPU or a supported format that a GPU can handle.

1Gbps for the MBE should be fine. your HD streams max out at under 20
mbps and so streaming 5 of them + overhead is a bit much for a 100

Depends. If you're using a nvidia card with VDPAU and supported
content, not a lot, but it's best to plan ahead for being able to have
the CPU handle the content without the GPU. a core2duo in the 2ghz
range should be fine.
