View Full Version : New MythTV Spec Check

January 27th, 2009, 09:23 AM
Hi All,

This is my first delve into MythTV and I am hoping that, with your help, I get this right first time. I have looked at a number of the other posts regarding machine builds and come up with a build that should work - just wanting you to run your expert eyes over it and see what you think and any changes you would make.

The general idea is that I am looking for an ultra quiet and energy efficient machine that will record UK freeview (DVB-T), play mp3s, ripped DVDs (iso's probably) and stream audio and video out to other units around the house. Maximum load (as far as I can tell) would be two digital TV stations being recorded/viewed and two dvd movies being played at the same time (one locally and one remotely). This unit will be both frontend and backend.

Considered spec:
MB: ASUS M3N78-AM with GForce 8200 onboard uATX
CPU: AMD Athlon X2 5050e (2.6GHz)
Mem: 2Gb (PC2-8500)
HD: 1TB WD10EACS Caviar Green x 1 (for now)
Case: Antec NSK2480-UK Desktop media centre case (380W PSU)
Tuner:Hauppauge Nova-T 500 (dual digital tuner)

Additional frontend unit: ZyXEL DMA-1000 UPnP media player

At the moment I have traditional TVs (not HD) though I will consider an upgrade to an HD TV in the future. I will also be running all connections over a Gigabit ethernet.

There are a couple of questions though:

Would it be better to have a dedicated PCI-E graphics/network/sound card?

What would it take to boost this to run HD?

Many thanks

Your machine should run recorded HD just fine. If you want Blu-ray HD, then you might need to use VDPAU, which I don't think has been backported officially to 0.21 yet.

IIRC, The 8xxx series of nvidia cards support VDPAU, but since yours in onboard i'm not sure.

You might want to check out the noise from your hard drive - I've settled for Spinpoint drives in my Myth PC... whisper quiet :).

I agree with the previous reply you should be ok for HD, I've just upgraded from nova-t 500 to nova-s plus. BBC HD playback is good (75% load on AMD 4200+).

Thanks, Steve.

Many thanks for the replies :) Sets my mind at rest :)

I have been toying with two different boards - the one specified above and this one: Asus M3A78-CM (http://www.asus.com/products.aspx?modelmenu=2&model=2341&l1=3&l2=149&l3=736&l4=0) which has an Integrated ATI RV610 which supports an RGB output.

Any idea how well this ATI chipset is supported? or would it be better to go with a separate graphics card such as an NVidia GeForce 8400GS (http://www.asus.com/products.aspx?modelmenu=2&model=2094&l1=2&l2=6&l3=551&l4=0)?

What is the composite video output on these cards like?

Many thanks
