Developers / DHCP leases info page for web admin
« on: August 23, 2009, 06:10:33 pm »
I have created a basic info page in the web admin for DHCP leases. I still have to add actions of some sort, so looking for some input there. Am planning on at least puting something in to add static reservations for devices that dont support dhcp, and probably an option to remove old stale entries.
This will be available be in the next build.
Any feedback would be highly appreciated.

Developers / Help needed: DVD Installer
« on: June 27, 2009, 05:59:12 pm »
I started work on a DVD based quick installer for 0810, but am having a hard time finishing it up.
What I could really use is help from someone who has experience with customizing the debian/ubuntu preseed installation method as used on the ubuntu "alternate" install CDs.
If you are this person, please take a look at and give your input, this is the last big hurdle for getting a beta out the door.

Users / DCERouter using too much cpu
« on: June 22, 2009, 05:38:47 pm »
Ever since the last alpha release, I have been having problems with DCERouter going nuts and using up all the cpu. This is usage in excess of 180% as reported by top, with loadavg's greater than 60. No functionality seems to be missing and there are no other adverse effects to the system (other than obvious problems playing media with no cpu time available) so I dont really know where to look.
The log shows this:
Code: [Select]

repeating over and over every 30 seconds or so. No errors in mythtv logs. And mythtv still works as it should while this is goiong on (again, other than severe stuttering).
Any ideas?

Developers / New boot splash graphics
« on: June 03, 2009, 05:56:55 am »
Having Kubuntu boot splash graphics has bothered me for awhile, and i finally got bored enough to see about changing it.
I have been working with bdfoster on irc to come up with some ideas for this, and we have the following rough draft:
Please let us know what you think, good or bad!
In the end this will be all packaged up into a .deb and hopefully included in the release ver of 0810.

Developers / 0810 MythTV storage groups discussion
« on: April 30, 2009, 11:13:08 pm »
Was working through some issues I was having with storage groups only to discover that i ended up fixing a known issue (I really need to read the release notes more often), but at least I learned alot about how the storage groups work. That said I do have some suggestions to make or at least wish to start some discussion on them while I implement them in the scripts.
In response to the following:
"One last change is in the "Default" storage group - it no longer points to the drive with most space. This was changed because eventually it would throw mythweb for a loop once the paths changed. I will look into a better way to defaultly record to the drive with most space, most likely using recording profiles."
It is my understanding that MythTV will always choose the device with the most amount of free space, given that all other weights are equal, and that all dirs are in the same storage group. thus the easy solution for the above problem is to simply put all public/tv_shows/[device] dirs into the "default" storage group. I have tested this out on my setup and it works perfectly.
This information was gleaned from and
It would probably also make sense to add the same set of dirs to the LiveTV storage group so that Myth can manage them properly as well.
One additional change I made to my system was to give the system drive an artifically high weight so that it will only ever be used if everything else is full, but this is just because i have a very small system drive in my test rig (17 gig). Its a very easy thing to do as it is just a single line that lives in mythconverg.settings and would be exactly the same for every install so could be included in the install if this is something that the average user would want.
Overall I am very impressed with the way MythTV has implemented these storage groups, it is way more flexible than I initially thought possible and the weighting system is very well designed.
I would like to see some discussion on this from developers and users alike.

Users / HDHomeRun IR receiver
« on: April 14, 2009, 12:13:24 am »
I am replacing my PVR350 tuner with a HDHomeRun and as such would like to switch from using the PVR350 IR receiver to using the same remote with the HDHomeRun IR receiver (at least until the gyration stuff is mature). I followed the directions here but still no go. the "udp" device fails to start during a router reload. I had seen a message in the log for the udp device early on that seemed to indicate it didnt have any remotes configured, whatever that means, but now it is not writing a logfile at all. I intend to continue using the "lircd.conf.hauppauge" (template 360) as that matches my remote and worked fine previously. I can run lircd manually and use irw to view the remote commands, but lmce does not respond to them.
I am wondering if i am doing this step correctly: "From here just add your remote config file with proper linuxmce mappings and you should be all set." as I am not sure what to do. I have clicked the "add remote" button for the MD and chosen the lircd.conf.hauppauge device.
I have looked over the wiki but have only found advanced info on creating new devices, not the proper use of existing ones, but perhaps i missed something. Any pointers?

Users / dynamic dns
« on: October 31, 2008, 04:24:35 pm »
So, are the dynamic dns clients really only meant to be used when the core has a directly accessible public ip address on its external interface? This seems pretty limiting to me, as most installs are going to involve a cable modem or dsl router in front of the core which serves it a private ip.
I setup a dyndns account last night and initially set it up with the external ip it autodetected (207.something, iirc). Then I setup dyndns info in the dynamic dns section of the web admin. Now I see this morning that my dyndns address resolves to (the ip given to the core by my dsl router). Did i set something up wrong or is this service just completely useless for the majority of users?

Users / Character LCD/VFD displays
« on: October 24, 2008, 11:10:04 pm »
Is there anything in LMCE for parallel or usb driven auxillary character (or graphic even) LCD/VFD displays? I see that one of the Fiire systems has a VFD, and just kinda got curious if theres something built in or if its something specific to their LMCE builds. In its previous life, my current core/hybrid hardware was a MythTV box and I did at one point add a parallel attached 20x4 LCD to it. Not a make or break deal for me at all, just looking for an extra bonus :) I can always crank up LCDProc like I used to I suppose.

Users / drive mounting/unmounting

Why are my drives being mounted/unmounted repeatedly every few seconds?

Users / Gyration MCE idea?

Just saw this on hackaday:
Looks pretty cool, any idea if it would be possible to get it to worrk the same with LMCE?

Installation issues / Control DirecTV receiver via serial
« on: October 03, 2008, 06:52:00 am »
I am working on switching to LMCE from my existing pure MythTV setup, but am not quite sure how to get LMCE to control my sat box. Currently MythTV calls an external perl script that simply accepts the channel number as its only option, and creates a data packet to send to the box over a connected serial cable. If the channel change succeeds, the script exits normally. If it fails, the script exits with an error.
The box is a RCA, model is D10-100 (yes, it is quite old. I passed on a free upgrade recently because I really like the serial control). I was unable to find an existing template for this system. I did poke around in the generic serial device, but it really doesnt make sense to me (and I am a programmer by trade). Is there some option I am overlooking in LMCE, or do I just set it up directly in MythTV like I have it in my current setup?
