I am having no problems with ui1.  There are issues with ui2 and 0810.  The intel drivers will need to be updated and that will likely happen when 1004 is released.

Thanks for the files. It works great on my core. But different story when it comes to my MDs. Can't play any DVDs on them after updating them. (unfortunately, I didn't backup the files on the MDs) One of them is 64 bit. Any ideas on troubleshooting?

I believe the 12-12-2009 update replaced the pluto-disk-drive package which would, I think, overwrites a file supplied by Itsik.  So if you update your core or MDs it could prevent some of this functionality.

I havn't tested this since the 12-12-09 update so I'm only speculating.

My UIRT works just fine pointing into the room (red led towards the couch) without the Xantech emitters.  Of course, ymmv, if you have issues you should use the Xantech emitters as posde suggests.  Try it.

Scenarios are only generated for MDs which are in rooms.  If AVWizard crashed and you hacked past it then you never made it to the Setup Wizard to tell LMCE what room the MD is in.  You can either run the Setup Wizard from 'Advanced->Setup Wizard' using the onscreen Orbiter or...

Check the webadmin under Devices->Media Directors, each MD needs to be assigned to a room.   Each MD has a pull-down menu selection bar under the Device/Room heading, this is where the 'room' is defined for each MD.  If it says '- Please Select -' then the MD is not assigned to a room.  If you set the room in the web admin and then reload the router then regenerate all your orbiters the Media Scenarios should show up. 

Recently I added an MD and it didn't reach the setup wizard (I don't know why) and I set the room through the webadmin, reloaded then regened and the Scenarious appeared.

HTH.

Installation issues / Re: HVR-4000
« on: December 11, 2009, 07:09:59 pm »
Looking at the Mythtv wiki it looks like a little work is needed (firmware must be extracted from the windows driver for use in linux):

http://www.mythtv.org/wiki/Hauppauge_HVR-4000

and it also references:

http://www.linuxtv.org/wiki/index.php/Hauppauge_WinTV-HVR-4000

which provides instructions on extracting and using the windows firmware...

It would be great to package this up properly so the card is plug-n-play in LMCE.

A dumb question - what audio is on Bluray DVD's ?  (did not have time to research it)

From wikipedia (http://en.wikipedia.org/wiki/Blu-ray_Disc#Audio):
Quote
Audio

For audio, BD-ROM players are required to support Dolby Digital (AC-3), DTS, and linear PCM. Players may optionally support Dolby Digital Plus and DTS-HD High Resolution Audio as well as lossless formats Dolby TrueHD and DTS-HD Master Audio.[57] BD-ROM titles must use one of the mandatory schemes for the primary soundtrack. A secondary audiotrack, if present, may use any of the mandatory or optional codecs.

So by default all BD must use a format which is supported over S/PDIF (ac3, dts, 2ch-pcm).

OK, that explains why there is no audio when playing theese 5.1 clips :
http://www.h264info.com/clips.html

Yepper.  Although I do get audio when I play them, I only get the L&R channels in LPCM format through the S/PDIF cable.

I use the Fantastic 4 720P trailer and one of the I am Legend 1080P trailers, from that site, for my testing.  The FF trailer plays with audio just fine because it is stereo.  The I am Legend trailer only passes the L&R audio.  Anything encoded with multi-channel (>2ch) AAC will act this way (wrt audio).

Not sure if this is of any help, Onkyo seems to support AAC.

Many, many receivers support AAC... through Ethernet UPNP and USB.  I've not found any device that supports AAC over S/PDIF, I don't believe it is possible.

I did some playing and a little php/html learning and have altered the script to the point where it outputs a file I can save.  This part was pretty easy.  I don't know if the output is correct as I am not very familiar with the database.  I am unable to import the resulting file back into the database as I am getting sql errors on insert statements.  I am looking into this and will post any progress I make.

Progress report, what I know so far:

After much searching I havn't found a single Receiver which supports 6ch AAC over S/PDIF (exceeds the spec bitrate it seems).  And the current method xine uses to handle AAC via S/PDIF causes it to output in PCM mode only sending the L/R channels, no centre, no rears, no sub.  An HDMI audio connection should not be affected by this as it can handle 6ch of PCM.

There are three ways to deal with this:
1) Use analog 6ch outputs from the MD to the receiver and configure ALSA accordingly (best sound quality, I don`t think AVWizard supports this currently but I havn't checked)
2) Have xine re-encode the AAC to AC3 (or DTS preferably) for S/PDIF output 'on-the-fly'.
3) Have xine down-mix to 2 channel stereo for PCM or analog output and de-coding by a Dolby Pro Logic dsp.  (I REALLY don't want this)

I don't have enough cables, currently, to test #1, and I'd rather not do it this way (even though this gives a much higher sound quality due to lack of compression).  My cats love to chew wires and the fewer I have the better.

I would prefer #2 above but I have not figured out how to implement this functionality in xine_player (or even if xine has this functionality).  This is easy to implement with MPlayer (but would require playing all .mp4 files with mplayer... not desirable.)

So...  I am slowly reading up on xine and trying to push my way through (learning) some c++ coding in the spare time I do have.  For now I am resorting to playing .mp4 files with 6ch AAC using mplayer from the command line.  But I am hoping to figure a way to have xine convert 'on-the-fly' when an S/PDIF output has been selected in avwizard.

Thanks Thom, the plasmoid was the only way I knew how to return to orbiter short of a 'quick reload' from the webadmin

On to LinuxMCE related stuff:
- After entering KDE - How can one properly get back to LinuxMCE Orbiter?

There is a package called lmce-activate-orbiter-plasmoid which you could install to add this functionality, it is not installed by default.

Code: [Select]
apt-get install lmce-activate-orbiter-plasmoid

Then right-click on your kde desktop background and choose 'Add Widgets...' and choose 'Activate Orbiter' and it will add the plasmoid to your desktop.  Clicking the plasmoid should return you to the orbiter.  Works for me with UI2 on my core.  YMMV.

MAIN QUESTION: How do fellow LinuxMCE users configure MythTV for first time use? (mythtv-setup)

- I've recently learned about /usr/pluto/bin/Restart_MythBackend.sh
How is a user supposed to run mythtv-setup if mythtv-backend can't be stopped without Restart_MythBackend doing its thing?
- In my case, in Belgium, using dvb-t and a Hauppauge HVR-4000 we have to use a workaround to get program information into mythconverg (mc2xml)
- With the new myth 0.22 version, multiple frontends are supported (THANK YOU!!)
However, after killing restart_mythbackend, after stopping myth-backend and entering mythtv-setup, I am
100% able to choose the correct /dev/dvb/adapterN/frontendN. Problem is the adapter is not recognized, so scanning channels is impossible.
- When leaving myth-setup there is a warning like:
Code: [Select]
"Path /home/user_1/data/pvr does not exist" solve?This path off course does exist, but the initial user has no permission...

There is a common misconception, especially for people who are familiar with mythtv, about how to run mythtv-setup in LinuxMCE.  I got stock on this for a long time.

In LinuxMCE mythtv-setup should always be run from the 'Computing' menu in orbiter.

If you do this it will run with the proper permissions and some LinuxMCE script additions will deal with things like Restart_MythBackend automatically for you.  Your file permissions issue with /home/user_1/data/pvr should also be taken care of by running mythtv-setup from the computing menu as it will be running with proper permissions.

I know this is digging up an old topic but I've been trying to use this feature to backup my TV and Receiver device templates in 0810b2 and I'm getting some errors and no apparent output file.

The output I'm getting is here: http://pastebin.com/m2039a033

I'm thinking of doing a fresh install and would love to backup these templates first.  Is this working for anyone else right now?

Works great!  I was able to play the same divx movie (on CD in the core) on 3 MDs simultaneously with no issues.  I don't have optical drives in any of my MDs yet. Great work!
