Well,

high availability with Open Source should be quite common. There are several Projects and papers about this issue.
I wrote my diploma thesis about that *siiggh*, where i compared three Solutions for a HA-framework.
Redundancy in mind, it should be determined first, what's important to keep alive. The core? The DB? The Filesystem?both? How about the TV Cards (keep in mind THE week w/o TV!)?. The easiest way to increase HA is to go for RAID 1, hoping Murphy won't grill both HDs, so you just can keep a second "standby" Core and switch HD, rebuild RAID1.

Things like heartbeat etc could do the trick as well.
The "winner" of the conclusion was http://www.openais.org, an opensource implementation of the Service Availability Forum, as the idea was to keep several independant Software Moduls online.
The company i worked for never implemented anything based on my thesis .... i wonder why ;O)

Havin' this in mind... HA is pure pain!

Some literature:

and a presentation: http://www.linux-ha.org/_cache/HeartbeatTutorials__LWCE08-ha-tutorial.pdf

I appreciate your advice Collin!

this just matches my "experience", as i said... 24 "sounds" cool ;O)
At least, i know my LCD can handle it.
I just wanted to share, what's "possible", and how.

Thanks for your help and advice...

Pat

I just found some more settings...
Use them at your own risk:

Code:

Modeline "1920x1080@25" 74.25 1920 2560 2608 2752 1080 1084 1089 1125 +hsync +vsync
        Modeline "1920x1080@24" 74.16 1920 2558 2602 2750 1080 1084 1089 1125 +hsync +vsync
        Modeline "1920x1080@50" 148.5 1920 2448 2492 2640 1080 1084 1089 1125 +hsync +vsync         
        Modeline "1920x1080@60" 148.5 1920 2008 2052 2200 1080 1084 1089 1125 +hsync +vsync

I still try to find out, what fits best to my needs.
24hz "sounds" cool, but actuallly, the picture is a) slow b) not smooth as with 50Hz OR 720p.
So i think a need a new graphic card... ;O(

Colin,

i just add the settings to http://www.mythtv.org/wiki/index.php/Modeline_Database#Sharp_LC-37X20E .
Hopefully you ment the mythtv Modeline DB, as I couldn't find something similar at linuxtv.org .  ;O)

Pat

LegoGT,

your hint was just what I needed. I knew, that the modelines are the problems, but with your perfect "for-noobs-walk-through"... my LMCE just looks as pretty as possible!

Ok, for the record :

Sharp LE37X20E

Code:

Section "Monitor"
    Identifier     "Generic Monitor"
    Option         "DPMS"
Modeline "1920x1080" 148.5 1920 2448 2492 2640 1080 1084 1089 1125 +hsync -vsync
HorizSync 20-500
VertRefresh 50-61
EndSection

Horizontal:
-- front porch: 528
-- active pixels: 1920
-- total: 2448
-- sync width: 44
-- polarity: +

Vertical:
-- front porch: 4
-- active pixels: 1080
-- total: 1125
-- sync width: 5
-- polarity: -
backporch
Pixel Clk: 148.5000

so, colinjones, LegoGT.... you really made my day ;O)

Patrick

Thanks guys!

I'll check tonight if i can slap my system once more with your help!
I keep you updated. ;O)

Patrick

Dear all,

i just installed LinuxMCE another time, just to check if screwed my system once more ;O)
As i recently bought a new LCD, i would love to make use of the 1080 resolution.
But the moment i switch to 1080, the picture starts to show a black bar on the left side.
It just looks, like the picture is move to the right for some dozens pixels.
This just shows up when i set the LCD to pixel by pixel mode AND set the AVWizard to DVI, 1080, 60Hz.
In 720p the black bar is gone.
Does anybody in the community shares the same experience?
A work around is, to NOT use the pixel by pixel feature and setup the screen to my needs (reduce size, move left).
But i think, the picture quality is not as good.
I run the nvidia driver out of the box. Last time driver update did not help.
For checking my LCD, i installed WinXP with latetst nvidia driver, which gave me a solid 1920x1200 @ 50Hz 

Thanks for all your help and keep up the work... you guys rock! ;O))

Patrick

troca,

as far as I know, theres is no way up to day,making LMCE showing rared movies.
But things you could do are:
- unrar them while copying them to the linuxbox
- unrar them ON the linuxbox, using the shell and install unrar-free or unrar-nonfree
- creating scripts/template that unrar the files, after your favourite torrent clients finished donwloading.
(some torrent-clienbts offer these "things-to-do-after-finishing-download"...

Patrick

Ok... is Solved.
On these MSI 7329 board... you better do NOT have 128MB Texture Memory for the onboard graphics  in the BIOS ;O)
Amazing, how this did have effect on stability, video, sound etc...

Ok... lets rock... finally LinuxMCE works as suggested ;O))

Patrick

Dear all,

i just freak out with a strange behavior:
when i play a mp3 with high pitch like feist - I'm sorry, the sound
sux an the higher frequencies.
First i update the alsa driver/libs/utils from 1.14 to 1.16, no success.
After that i stopped LinuxMCE and played that mp3 with mplayer via ssh.
Result => PERFECT Sound.
When i start the LMCE Core Services the sound is still good...
The Moment i start the Media Station we're back to business... Sound sux.
This all happens WHILE playing that song.

Ok here are my specs:
MSI 7329 (MSI Media Live)
Audio Realtek  ALC883

I do connect LMCE via a chinch cable to my stereo

For now i did NOT test
-if sound sux with older LMCE Versions (7.10 always did)
-different wiring like spdif
-playing the mplayer mp3 via ssh with standarf LMCE goven ALSA
-if sound stucks on different MD

Does anybody else have this problem or could help me out here? ;O)

Patrick

Hey Guys,

are you going to  be around at linuxTag all days?I plan to check by and see thinsg working out.
I figured out, this would be cheaper to see an existing installation running, than buying the hardware on my own, just to get a look and feel ;O)
When are you starting, putting things together as the conferences starts on Wednesday 28th? *mejustnosy*

Greetings from Hamburg

Patrick

the user/pass/Pin given at the install are just logon data for LMCE itself, not for the ubuntu base.

Dear all,

i have the same experience with the MCE USB  receiver without the external emitters.
Does someone know, if that thing does work WITHOUT the ext. emitters?

btw... i'm running LMCE 710b4, and couldn't  teach LMCE to use tackle my Grundig TV
or Harman Stereo ;O(

Thx...
