MythTV Setup Guide/HOWTO

ok we have to be really really close, I get 90% green with parts of the picture in behind it.
I'm assuming it's that I'm pushing the card/machine/somthing too hard?

A quick test of mplayer /dev/video0 and sure enough I'm watching channel 2. and it doesn't look that bad. This is of course coming over the tuner not the svideo. I'll worry about that little issue later.

I guess next is to figure out why I don't have sound?

Never mind, channel 2 doesn't have sound is why I don't have sound

I guess it's time to get myth going and happy

Once again thanks for the help ipod and tv all working at once. This is great

I think that fb support is only meant for when myth is compiled for embedded use. You'll want to re-emerge myth without the fb use tag.

Howdy fellow gentooists,

I have a strange problem. Suddenly, for no particular reason, my PVR250 gives only a black screen in MythTV, but now has a new /dev/radio0 device! How about that?
After some logfile scrutinizing, i found out that things go wrong during the init of the saa7115 module (hence, no image). It should be found and registered as a client on the i2c bus, but it doesn't. Did anybody ever come across this weird situation? My MythTV setup is rendered useless by this, hopefully you can help me a bit further. I appreciate your help on this one

My setup is:

ASUS Pundit - P4 1.8 GHz
PVR-250 (rev. 1)
Gentoo GNU/Linux on a 2.6.8-r3 kernel (gentoo-dev-sources)
MythTV 0.16
ivtv-0.1.10-pre2-ck114s

As I said, the init of the saa7115 module goes wrong. Mythbackend and mythfrontend both complain about not being able to read from the decoder devive (/dev/video0). Modprobing ivtv starts probing for saa7115, but never finds it at the i2c address 0x21 like it should. I know for a fact that some lines are missing in the log, such as these:

Hmm- The modules.txt does say 'in general', and since it seems that it's detecting a radio device that's not there, might be worth specifying the options in /etc/modules.d/ivtv, at least to see if that's part of the problem.

I haven't tried any versions of ivtv past anything in ck's oldgoodones, but at http://67.18.1.101/~ckennedy/ivtv/HOWTO.ivtv-0.1.10 he still recommends some module load lines:

Hobbes-X, thanks for you insights, but as I was near the point of taking my PVR250 back to the shop, I thought: why not re-emerge the kernel, build it again along with the modules AND the ivtv ebuild that resides in Portage. The kernel now is 2.6.8-r7 instead of 2.6.8-r3 btw.

At first the ivtv modprobe produced a bunch of 'cannot allocate memory' errors in the log, but modprobe -r and then modprobe again did the trick: all errors gone, everything behaves as normal again. It seems my MythTV box just wanted to take a few days off and torture me

Anyhow, everything back to normal again with the ivtv-0.1.9-r4 ebuild (~x86) which is actually Chris Kennedy's ivtv-0.1.10-pre2-ck71d.

Cheers

Hi there,

I am setting up MythTV with a BT8x8 card (Hauppauge WinTV), and everything is going well so far. The one problem that I am having is with the Zap2it DataDirect service. I signed up at the web site and can browse my listings in mozilla, but Myth won't download them with the follow error..

Hi Frank-

Any chance that there's a character in your username or password that wouldn't have been escaped? Everything else should be fine if you're using wget-1.9.1-r2, and the same username and password.

hey guys ...

i can capture video fine ... i use the svideo out on my dishnet receiver and have that hooked up to my tv tuner card ... for the sound i have the 2 red/white cables from the dishnet receiver hooked up to the LINE IN on my sound card ...

how do i tell mythtv to get the sound input from LINE IN of the sound card and record that along with the video ?

scarr · Posted: Tue Oct 26, 2004 4:03 pm Post subject:

You need to use alsamixer or some other mixer to attach to Line.

In Alsamixer, you arrow over to LIne, press space to attach to that line.

Make sure that the Line is on Mute as well, otherwise you'll hear sound constantly.

YOu should see an M on the line.

Today i bought a PVR350 and some other hardware to build a real htpc. But when i try to compile mythtv i get a very strange 'thing':

A reboot solved my problem. I don't know how it can happen.

Here's a quick outline of how I got it working, went really quick after I figured everything out.

I'm using the 2.6.10 kernel so I didn't need any kernel patches to get this working.

I emerged ivtv and mythtv from portage, and both work fine. I then compiled everything that I need into my kernel, the list is listed in previous posts, so I won't repost that here.

Then finally I found that the biggest problem is in what order things are loaded. I made a little shell script that must be run as root to load everything when my computer boots up:

So, I'm not sure if I'm completely retarded, completely misguided, or just not seeing something that is obvious and apparrent to everybody else.

I can get IVTV working, the audio on my MB working, and even the ivtv-fb fb-out to TV from the 350. But, I FOR THE LIFE OF ME, cannot get lirc to work with ANY of the afore-mentioned HOWTO's...

My problem: lirc-i2c + 2.6 kernel.

Apparrently nobody seems to be having problems. I've searched the forums and only found a couple instances of people looking for the patches for the kernel.

I haven't found anything for the latest and greatest Gentoo 2005 install's... but, I figured the gentoo-sources (now 2.6.11esque) would have the same lirc-i2c stuff.. Nope.. nothing... so, I went as far as to regress to the 2004.3 gentoo live install.. Same deal...

I mean, I've been using linux for a LONG time... and I'm no idiot.. so much so, that it took me a LONG time to de-ego myself enough to post this message.

So, how... without using love-sources (I have bad luck with them) can I get lirc-i2c.ko? Is there a way? What I would prefer is a lirc-i2c kernel patch.. for 2.6.x, From what I know, one doesn't exist... and all of the links that WERE around for 2.6.9ish are either DEAD, or not valid anymore. In fact, the ONLY link that seems to work nowadays is THIS one.

Anybody?

Thanks,
Micah

I know that lirc hasn't been included in any offical kernels for quite a while. I had it working with 2.6.8 I believe, but I am having difficultly making it work with 2.6.10 vanilla.

Make sure when you emerge lirc you emerge it like:

Boy do I feel retarded.

LIRC_OPTS="--with-x --with-driver=hauppauge" emerge lirc

solved my problem.. Not sure why I never saw that before.. or if I never acknowledged it, but... that was it.. Verdict is in: I'm an idiot. hehe

Then again, I tend to get common-sense-blinded when I work on a project for too long. Yeah, thats it.. I'll use THAT excuse..

Thanks a lot ColeSlaw.

Has anyone used a DVB-C capture card? (Terratec DVB-C 1200).
We have some troubles recieving channel information.

Does anyone have a copy of the original guide? I'm getting a "Page cannot be displayed" when I click on it.

Currently, I have my M10000 running with the Unichrome drivers under X (I'm not bothering with a WM like gnome or KDE). I'm using the 2.6.15-gentoo-r1 kernel, and I have the streamzap remote.

Thus far, all those components appear to be working OK (as far as I have been able to test them). I'm looking for a good gentoo guide on installing MythTV on this box, and have been coming up empty for the last couple of days (lots of dead links everywhere).

What I haven't yet set up:

1. MythTV
2. lirc (installed but not configured (and complaining about undefined symbols))
3. datadirect (zap2it)
4. tv output
5. automatic log-in on boot which starts up mythtv (no keyboard / mouse, just a remote control)
6. This one may blow it all, but I'm also trying to figure out how to do this over a network boot, while currently it is set for a local hard drive boot (I intend to remove the hard drive). I suspect that this will have me start a lot of this over, but I'd like to get all my configurations set up and backed up so I really know what I'm doing later on. On top of that, there's a good chance that the only machine that I will have available to boot from will be running Windoze NT 4.0 (This is a machine I'm setting up for my father; personally, I'd be using FreeBSD). On the other hand, I may be able to set up an old 1st generation pentium running debian with maybe a few hundred megs of hard drive space and 16M of RAM...
