[mythtv-users] System Setup: Dual Opterons, Firewire, Xvmc, Homebrew Lirc, 64-bit packages, Hdtv (DVI to HDMI), Panasonic PT-AE700U Projector, Optical Digital Audio Surround Output

[David Ellis]

A general note on 64 bit MythTV.

 

1)       64 Bit MythTV works with some caveats.

a.       Xvmc drivers for Nvidia hardware (from Nvidia) are really bad with
current (7667) releases....hopefully this will improve later, but for now
64bit XVMC is spotty at best (it works every 5th or 6th time).

b.       MythTV itself is pretty stable on 64bit Linux (I run my backend
24x7 - I've had three crashes in three months - not too bad).

c.       Mplayer/Xine work, but have limited codecs for some third party
AVI's - basically anything that requires a 32bit codec WON'T work - until
the 64 bit implementations are more readily available.

2)       64 bit Linux is pretty mature with support for most packages:

a.       I run mtd for ripping DVD's

b.       Lirc

c.       Apache2 for mythweb 

d.       Asterisk

e.       X10 Home Automation thru CM11U and Firecracker

f.         Samba

g.       Postfix/Cyrus IMAP & POP

h.       WUFTP

i.         Tinyftp

j.         Sphinx2

k.       Festival

l.         phpBBS

 

To sum it up, if you absolutely must have the 32bit codecs (ie. You have a
lot of pre-existing AVI's), or you absolutely must have XVMC acceleration
for HDTV (I do my HDTV thru xv) you should go the 32bit route. Given your
processor specs, HDTV will be fine with a good Nvidia class AGP/PCI-E card
(5200 or better, recommend the 6600). For example my HDTV

I'm looking to put together the system to end all systems. I believe I have
spec'd out all the hardware, but I was hoping to get some feedback on
everyone's experiences with each individual aspect of the system. First I
will post the proposed specs, then the desired software / hardware behavior,
then questions that I'm concerned with at the moment. If anyone thinks of
something I may have missed, please let me know!

 

Also, as I build this I will be writing a guide. I am very much new to
linux, so it should be helpful to the "n00bs" in the community.

 

System:

 

Mobo: TYAN S2885ANRF (

http://www.newegg.com/Product/Product.asp?item=N82E16813151120 )

Proc:  AMD Opteron 246 SledgeHammer 400MHz FSB (
<http://www.newegg.com/Product/Product.asp?item=N82E16819103412>
http://www.newegg.com/Product/Product.asp?item=N82E16819103412)

Raid:  HighPoint ROCKETRAID2220 PCI-X SATA Controller (

http://www.newegg.com/Product/Product.asp?item=N82E16816115022 )

Ram:  Thinking around 1gb / chip

HD's:  4x400gb SATA For my "archive" ; 2x250gb SATA "working"; 1x160gb PATA
"music" ; 1x80gb PATA "boot"

Firewire:  Basic 4 Port controller (for hookup to my HDTV recievers)

Nic's:  Thinking the onboards should work, will add new ones if necessary

Audio: Need a recomendation here, onboard is Coax SPDIF, was looking for an
optical solution (longer run so i'm concerned about noise)

Graphics: Recommendations are good here too, I want DVI to HDMI for my
projector, as well as a second monitor running (for diagnostics, etc...)



Hi Matt-
As a noob who has the same mobo I'd love to see what you come up with.  I
haven't been able to get mine up and running.  Of course, the bulk of my
problems have been trying to get a PVR-250 running (which you don't have
spec'd).  The rest of the mobo stuff works great.

I had the same plan as you (although not quite as extensive in the
automation dept).  I bought the same mobo and CPUs.  I also bought a couple
PVR-250's, only to find out that this mobo only has 1 slot compatible with
the cards.  I've been trying on and off since April to get this working.  My
wife and and I had our first child in March, so their hasn't been much free
time for me to work on this.  I tried the 64-bit OS route and found that I
didn't gain much except a headache (be careful of some of the software
repository issues regarding the 64-bit distros), so I reverted to the 32-bit
versions.  I've tried FC3 (jarod's guide), knoppmyth, gentoo, and suse 9.3.
(And I'm about to try the new version of MythDora).  I couldn't get any of
them to work with either of my PVR-250s.   It's been a couple months since
I've last attempted an install, and I'm sure much has improved in the 64-bit
area since then so good luck.  I'm not a linux guru, which definitely
accounts for some of the delay in getting this to work.  My guess is that
you will have better luck.  


Greg
