TV has black screen followed by "MythTV is having problems. reset backend?"

[fearingsept]

I have had myth TV working on my system using the same hardware on ubuntu in the GNOME desktop. Since I installed LMCE I have not been able to use the TV feature. DVD's play fine. I closed out of my Orbiter and tried using the Kubuntu desktop and still I have the same problem.

"MythTV is having Problems. Reset the backend?

I have tried reseting the backend to no avail.

I am still using UI1 interface. I don't know if that would make any difference.
I have a Hauppauge 150 tuner card.
Someone please help.

You could try running "mythfrontend" from a terminal (konsole) under the KDE desktop.  That should tell you more about what's wrong.

Here is the output from the Konsole

Does this indicate anything wrong? I am uneducated.

Yeah, it doesn't work for me. MythTV eventually times out to the MythTV menu. I still suspect my video card. Just waiting on my Nvidia card to get here from New egg. Hopefully it works out.

[fearingsept]

So I got the new video card and installed it. I have the latest NVIDA drivers loaded and still when I go to tv I get just a black screen and the "MythTV is having Problems. Reset the backend? error.

[fearingsept]

Ok, So I found that I had some other problems with my video drivers. Long story short I reinstalled LMCE because I was unable to resolve the video driver issues I had. So now on a fresh install trying to use the Myth TV function in LMCE using a Hauppauge 150 tuner, what exactly do I need to configure in the Myth backend? I just want to make sure I have it right. I already put in my username and password to download the program guide and that part is working. Someone please give me some suggestions.

Also, Keep in mind that right now I am not connected to my cable TV because I am actually doing the installs at my office. So on earlier installs of a standalone Myth TV box I would just get static. Does LMCE look for some kind of input signal or should it work the same as before?

Thanks

After much troubleshooting and a good deal of reading I finally figured it out. Here is the solution for anyone else that might have this problem.
When installing LMCE for some reason it did not detect my Hauppauge 150 PVR correctly. I kept trying to reconfigure my settings in Myth not realizing that the video card information was incorrectly loaded. Instead of using an MPEG format for the card LMCE detected the card as some other format that I did not recognize.
To fix it I logged in to my admin page and under wizard/devices/Media Director I deleted my capture card.
I restarted the computer and LMCE detected the card as if it were just installed. Went through the configuration wizard again and finally it worked.

It seems dumb and simple now but the whole time I assumed that it was a problem with Myth TV and not LMCE.

I hope this information is helpful to someone.
