Re: [vox-tech] HTPC/Media Center build questions



Bill,

Wow.  Lots of info. Thanks!

I've focused on a few of your points...

You don't like Intel or ATI for GPU.  I'm a fan of nvidia myself.  
However, I'm also a fan of Asus and I can't seem to find a good nvidia 
HDMI mobo from Asus .  Gigabyte seems to only work with ATI. I'll keep 
looking.  (Asus and Gigabyte are the only two mobo brands I've worked 
with.  I know there are others, are there brands you recommend?) (My 
current compromise, to have a quad core CPU is 
http://www.newegg.com/Product/Product.aspx?Item=N82E16813128397 but it 
has ATI graphics.)

I have to claim ignorance about the real time encoding.  Do you have any 
more information on it?  How is real time encoding 
implemented/where/when would it be used?  I'm not sure if this will be 
something I'll need or not.

I'll look into the ION2.

The Intel atom ITX boards you mentioned.  Can you give me some 
examples?  (The boards have little or no expansion....for a TV tuner card.)

Thank you for your help, please forgive my ignorance.

Aaron
