Title: Message

The 7667 version of the 64bit Nvidia driver fails with authorization errors 5 out of every 7th attempts to use it with XVMC (works fine in raw XV mode).

 

The following link provides the details: http://www.nvnews.net/vbulletin/showthread.php?t=51032

 

The thread is long (the bug has existed thru several releases) – but still current. If you skip ahead to the last page you’ll see that the problem still exists with Version 7667. I have confirmed this.

What exactly do you mean "XVMC is spotty at best (it works every 5th or 6th time)."? Is it that every time you try and play a video, it takes 4 or 5 tries for it to appear?

 

The 80gb is just a spare drive I have :-D

 

Anybody have any idea if it is possible to dual-head, with mythtv on one head and the standard desktop environment on the other? I'd like to be able to monitor log files, display system information, etc on a second monitor.

 

Also, the dual processors were aimed at speeding up encoding (I would like for it to be able to keep up with the rate at which I record shows, ie encode a show every 4 hours or so MAX, + encoding DVDs

 

Thanks for the feedback so far guys!

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:

 

Proc:  AMD Opteron 246 SledgeHammer 400MHz FSB ( 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
