I tried this on my production system with about 41000 rows in the pluto_media table.

The indexes have reduced the period of time mysqld pegs my processor at 100%.

I monitor my core with monitorix and rrdtool, it's a P4 2.8G hyperthreaded cpu with 1GB ram.  It looks like adding the indexes created an average reduction of ~7% kernel usage, load average has dropped from about 1.0-1.1 average to 0.6-0.7 average.  IOWaits have also been cut in half of what they were.  The one day change is noticeable looking at my week and month summary charts.  I'm going to keep my eye on it to see if it's consistent.

Just as Andrew says.

I really like my Zotac ION 330, VGA, DVI, HDMI, Optical Digital.  I have not tried the HDMI video or Audio myself but others have here on the forums.  Netboots without a HD, quiet (the 330 DOES have a heatsink fan,  but its quieter than my PS3 at idle), low power consumption (~24Watts idle, ~26 Watts in 1080P decode with VDPAU).  I highly recommend it.

The Acer Aspire Revo is a really nice unit in a great VESA mountable form factor with a hard drive and ION graphics, the only reason I didn't go with the Revo was that it did not support the optical digital output I currently use for audio.

I highly recommend an ION based system for a Media Director for use with HD content in a small form factor.

How should I install a core system with the new linuxMCE distribution (I have some previous experience in installing 710 version).

There is currently no option to install a core only system.  You may be able to install a complete hybrid and then turn off the media-director portion of the system in pluto.conf.  I think that many people are simply installing a hybrid with UI1.

I have noticed that on my system /usr/pluto/bin/ takes a lot of CPU.

Have you checked to see if more than one copy of the script is running?  I had this issue after an update about a month ago and found that 2 copies of the script were launched.  I did a 'sudo kill xxxx' to kill the 2nd process and my CPU usage dropped to normal levels.  I think I performed a re-install and the problem did not return afterwards so I am unsure what caused the 2nd script to be executed in the first place.  If I recall correctly I had 2 copies of many things that launched erroneously on boot during that time period.

Would there be any incompatibility using the 2.28 kernel (from jaunty)? On another partition i tested kubuntu 8.10 with 2.28 kernel and got hdmi audio working.....
TIA, Paulo

I don't know enough about your graphical issues/questions to comment right now, but I am running kernel 2.6.31 on an MD and have had no problems/issues/conflicts of any kind.

2009-11-03 15:12:53.708 Source 1 configured to use only the broadcasted guide data. Skipping.

Run mythtv-setup from the computing menu and make sure you have your source configured properly.  Mythfilldatabase doesn't think you have an external epg source defined.

Hmm. I followed this, and changed the root pw, but this isn't reflected on the MD. Do I need to 'rebuild  image' on the admin site?

If you rebuild the image from the admin site the root password on that MD will be reset and you will have to perform these steps to set the root password again.

That's good to know. Do you have to go through Advanced -> IR Codes to contorl your AV Equipment?

Nope.  Once the device templates are properly defined and you define the audio and video pipes correctly in Web Admin -> Wizard -> Devices -> A/V Equipment - Connection Wizard, LMCE will automatically turn on/off devices and set the proper inputs on all the devices it knows about... automatically.  Then I use my tablet or webdt or nokia (or mce remote, etc...) to change channels or access my satellite receiver and LMCE sends all the IR commands automatically.


Installation issues / Re: black screen with cursor after avwizard
« on: October 30, 2009, 06:56:01 pm »
hi there - I just installed fresh 810 from the dvd, rebooted and went through the avwizard. Avwizard finished, and it hasn't done anything since then - just sitting there with a black screen and white arrow cursor, but nothing else going on. I can access web admin page, but there are "no users in database", so clearly it's not properly configured.

What do I do? just hard reboot? reboot from shell?
continually stymied,

First of all welcome to LinuxMCE!

The system is undergoing a lot of development right now and many issues have surfaced that people have been working through.  I have not encountered the issue you speak of myself but... I would first suggest doing a little searching on the forums for your issue.  A search of "black screen" brings up a bunch of posts which may relate to your problem:

Topic: SOLVED: Black screen with mouse pointer on Core (0810 alpha 2.31)

Topic: LinuxMCE Black Screen (Solved)

Topic: [solved] Black screen after starting X-Server

Hmm, are you using an nVidia card?  This poster had an issue similar to yours and found a solution.

Check that last one first if you`re using an nVidia card.  

Good luck!

Sorry Thom, I should be more specific, I was referring to Xine plugins (filters), not the xine_plugin of LMCE.  ;-)

In terms of the IR learning codes, you may need to follow the directions below before attempting to learn the button codes. I'm sure this fix is already in 810, but it may not hurt to try.

Learning works OOTB in 0810, the fix is included in newer kernels.  

I just tested my USB-UIRT without the Xantech emitters as well and all my devices are still controlled perfectly with my USB-UIRT pointing out into the room (away from my IR devices).

Great idea Thom, I was thinking along those lines.  I'm still trying to figure out if this can be done with Xine plugins or not.

Can anyone say that the have complete control of their equipment using a USB-UIRT?  It won't even learn codes (well, it learns them, but they do not work when tested.).

I have complete control of my equipment with a USB-UIRT, I am running 0810 Alpha 2.37.  The pronto code format is described in great detail in this article:

I use IR emitters connected to my USB-UIRT so the IR codes are sent directly to my devices (within inches).  I have read that the USB-UIRT can have problems sending IR codes to devices without the emitters.  This is likely due to a couple of different issues: attenuation of the IR signals and reflections or scattering of the IR signals, all will interfere with transmission.  Have you tried pointing the USB-UIRT at the television's receiver from a few inches away?  Another thing to verify: ensure that the timing information is correct in the codes you are using, the pronto article describes how to verify this.  You may also try some other Sony TV codes from's IR Hex code database.

You may also want to check the Com port settings in LMCE for the USB-UIRT, some people have had it change ports on them and stop working, check out:

Good luck.

Your tip in irc the other day led me to the same article.  The pronto codes are fairly simple to decipher and easy to chain together.  Thanks again!

Can you explain the 1st, 3rd, 4th, and 9th step in a bit more detail? I am not sure I understand due to my lack of Linux experience, what it means Make changes to /include/config/hardcoded.php to allow setting of auto and vdpau support as HW acceleration through lmce-admin and so forth. I think that just a little more detail would do. Also, are there any other steps that need to be performed?

This is not supported by the devs in any way untill it's released and I don't really recommend this is if you don't know what you're doing but...  if you really can't wait.

1) The file to edit is on the core under the /var/www/lmce-admin directory, it's part of the webadmin configuration.
3) Add the avenard repo, see:
4) I think brandons builds are in the nvidia-vdpau launchpad ppa repo, google search should find it with instructions for adding it.
9) Do the same as step 8 only to the file referenced in step 9.

Step 1 is performed on the core, all other steps on the MD that has vdpau capabilities.
