MythTV

Help & support for Ultimate Edition 1.9


MythTV

Postby buschbarber » Fri Jan 16, 2009 10:25 pm

I have been using Ultimate 1.9 for some time now and I have been fascinated with the operation and features of MythTV, as a DVR.

Recently switched some drives around and disabled my Grub Loader, so I was offline for some time. Once I fixed that, I booted Ultimate and installed 49 updates. Everything seemed to be working fine until I tried to launch MythTV. When I chose Watch TV, the icon did nothing, so I checked the Myth Backend to see what was wrong.

My WinTV-HVR-1600 TV card was not being recognized in the Capture Card section. When this has happened in the past, I followed the procedure to reinstall the Firmware CX18, as outlined on the following site:

http://www.mythtv.org/wiki/Hauppauge_HVR-1600

When I came to the part in the Compiling section, sudo modprobe cx18, I received an error that it could not find cx18.

At any rate, I finished the list of commands, without further error, but when I go to the Backend, and choose the Mpeg2 encoder card PVRx50, PVR500, /dev/video0 does not display for Device and the Probe fails.

Does anyone know how to fix this.

By the way, I switched to XP PRO and the WinTV app works there, so it is not a problem with the TV card.

Other than re-installing Myth TV I don't see a fix. I have had Myth stop working at various times for no particular reason and always had to re-install it from scratch to get it to work again. It is very quirky at best.

Sounds good!!

I notice you are running an Asus motherboard and a 6600 QuadCore processor. Last year, when CompUSA closed their retail store in my town, I bought an Asus Striker Extreme motherboard. This year, I bought 4Gb of Corsair memory and an XFX Gforce 9600GSO card with 768Mb of ram. I plan to buy the Intel 6600 QuadCore cpu.

I am hoping that system will solve some of the problems I have had with Ubuntu not recognizing my 8400GS PCI card, as well as improve the performance. Currently, XP Pro works fine with the 8400GS and outputs to my 50" HDTV with no problems (DVI to HDMI). I would like to output Ubuntu to my HDTV, especially if I use it as a DVR. MythTV was working very well, especially in the area of Flagging Commercials and stripping them from my recordings, It also let me burn DVD's without Commercials. The DVR in my cablebox does not let me do that.

I successfully Uninstalled MythTV and ReInstalled it again, but it still refuses to recognize my WinTV-HVR-1600 card. It tells me "Probe Failed".

In the past, whenever the Kernel changed, and I had this problem, I just followed the procedure on

http://www.mythtv.org/wiki/Hauppauge_HVR-1600

and I was able to go into the MythTV Backend and get it to recognize the card again in the Capture Card section.

Nothing has changed with the card and everything else in Ultimate seems to be working OK.

WinTV still works in XP Pro.

The only thing I have noticed is that when I am Compiling

cd v4l-dvb
make
sudo make install
sudo make unload
sudo modprobe cx18

and I get to the sudo modprobe cx18, I get an error indicating it cannot find module cx18.

If I continue to follow the instructions I receive no further errors, but I cannot configure the Capture Card in the MythTV Backend.

You're not the first person to get bitten on the backside by an update.
That's why I only update things that need an update, I view it like flashing the bios... if it works like you want it to, don't mess with it.

Your update prolly included a kernel or header and that's why it won't recognize your module now. It was compiled specifically for the old kernel and needs to be recompiled for the new one. (dkms usually takes care of this)
Try recompiling v4l-dvb and see if cx18 gets picked up again.

It sounds like a kernel update has created the problem. Re-install with the old kernel and try again(and don't do anymore random updates).
