What's the realistic cpu/memory specs for a decent non-HD HTPC setup? I just need a way for the MIL to watch MSNBC, wifey to watch vh1 and food network, and maybe scifi for me( I'm not real big on tv). I know movies can be handled by netflix, and the local stuff by antanee(sp?), but what about the basic cable channels? Is there an outlet for that, that is "spouse-friendly"?
For basic cable channels, most are unencrypted and can be managed by your TV tuner card. Just plug it into your cable line and scan the channels.
For channels that are encrypted, you'll need to route the output of the cable box (which does the decryption) through the TV tuner card and control the cable box via an IR repeater that is controlled by the TV tuner card software. It sounds more complicated than it actually is.
Realistic system specs depend on the operating system you're planning on using. Many people are using low-power Intel and AMD embedded motherboards to build ultra-small systems.
The way they are able to do that is by leveraging the video card to do the heavy lifting, leaving the CPU to manage the rest of the system. So bottom line? Get a good video card and a good sound card to reduce the load on your CPU and you could run a Pentium III or a Celeron.
Give you an example:
I have 3 HTPCs at home. I got lucky and scored a bunch of spare computers that were being written off. So two of them are simple HP Pentium 4 2.4GHz small form factor PC's running WinXP. Cute buggers, HP D530's I think. So far, I've added: an HP USB Media Center receiver and remote ($20), a Wireless N network card ($15), a Sound Card ($5) and an ATI 3450HD half-height video card ($50). The hard drives are only 20gb (that is what was in them) in size and they only have 1gb of ram (managed to rummage through the pile of systems and mix/match memory to get that).
They've not failed to play anything, HD or otherwise that I've wanted to.
I keep one in the garage to play TopGear while I'm working on cars.
Bottom line? To watch/play TV on your PC you need the following:
Decent video card (128mb of video ram or better)
TV Tuner card
IR Remote
Wireless N or 100mb LAN network connection
DVD-Rom
Keyboard/mouse (wireless is nice)
A TV/screen capable of displaying the signal from the PC.
The rest is just adding the parts, connecting the cables and loading the software.
