Re: [vox-tech] Mythbox hardward compatibility

Its as if you are reading my mind.

I too am looking into building a pvr that has an ubuntu backbone.  I too 
have very little experience with linux however I am looking into a cross 
compatible box that uses windows 7.

Hardware that works in 7 is relatively easy as compared to Linux.  Finding 
such to work on both is a challenge.  I would first build it in 7 w/ 
beyondtv and once I established that I have it all working correctly then go 
Linux.  Heck getting 1080p setting in ubuntu seems hard in itself.

I was looking at the ati 5870 gpu that has hdmi output.  I have read online 
that you can get this gpu to have sound output but not sure how hard that 
would be to config in Linux.  I will probably go with a regular 5.1 sound 

I like your choice in mobos and gpus.  Evga is tops in my books.

You email intrigues me.  Hopefully we can coorespond and feed off of each 

Is there anybody in the group that has any experience building a pvr (dvr)?

Subject: [vox-tech] Mythbox hardward compatibility


I'd like to enlist your help. Knowing nothing about Linux, but having the 
desire to not pay Microsoft, I am committed to putting together my own HTPC 
from scratch. Searching the forums, I'm finding that the message boards are 
way past my level of technical expertise. I'd like to go what some flavor of 
Mythbuntu to avoid having to buy Windows.

The overarching goal is for me to build a PVR that can still surf the net. I 
don't have a lot of spare parts around so I'm going to have to buy them. 
That's ok though, because I want to build something that might be more than 
I need now, so that it will last 5-7 years without getting too outdated.

Inputs will be the internet and basic cable tv.
Output will be to a tv via HDMI.

Must serve as front end/back end
Turns on and off by itself. http://www.mythtv.org/wiki/ACPI_Wakeup
Needs to be installer friendly (I have zero linux knowledge).

Below are two TV tuners and a list of the three setups that I'm considering. 
I'm putting them out there for you to comment on, but feel free to throw out 
other suggestions.

Of course I will need a case, HDD, memory, PSU, and other misc parts, but I 
don't believe those will make any difference in compatibility.

TV Tuner:

Here are two dual tuners that caught my eye:

Hauppauge 2250 w/ remote
I read that the driver for this only supports the digital side of the tuner. 
First off, is this true that only the digital channels will work? Does this 
mean that I won't be able to watch any of the analog stations from my cable 
provider? What other cards that are still in production would work for both 
analog and digital?

Here's a link to my cable provider for reference. At the bottom is discusses 
the signal format.

SiliconDust HDHomeRun Network-based Dual Digital HDTV Tuner Ethernet 
This seems like a popular tuner on Newegg and I like the idea of having the 
TV stream through ethernet. Seems like the same problem as the Hauppauge 
with only supporting digital channels. Anyone have any experience with this 


1. Overkill
CPU: i7 920
Video: EVGA 512-P3-1213-LR GeForce 210 512MB 64-bit DDR2 PCI Express 2.0 x16 
HDCP Ready

Video: Is there a Nvidia driver for the GeForce 210? Can I get audio out 
through the HDMI?

2. More than enough
CPU: i5 670
Mobo: ASUS P7H55-M PRO LGA 1156 Intel H55 HDMI Micro ATX
Video: Built in Intel HD Graphics

Mobo: Any limitations (besides cases) using a mATX
Mobo/Video: Is there a driver for the Intel HD Graphics chipset? Can I get 
audio out through the HDMI? Will this output 1080p?

3. Pretty good
CPU: AMD Phenom II X3 720 BE
Video: Built in ATI Radeon 4200

Video: Is there a driver for the Radeon 4200? Can I get audio out through 
the HDMI?
