I spent a bunch of time this weekend working on my knoppmyth box.
I am using an chaintech 7nif2 with integrated Nforce2 and Svideo out. I also have 1 PVR-250MCE card).

Performed an auto install. After the install, I ran the install-nvidia script and got my video working fine. Ran through the mythbackend setup. Defined my tuner, video sources, inputs, etc. Next booted into front end. Ran mythfilldatabase without issues.

When I try to view live tv, I get a black screen for about 10 seconds and then it just goes back to the menu. Next I did a cat /dev/video0 >junk.mpg and was able to view a picture using mplayer on that machine.

Did some more testing and was able to copy video and music files to the box and play them. After some looking around at the forums I was able to get my cd/dvd drive working by changing the group for the device. The TV listings are populating.

So my problem is that I cannot view live tv. Don't know that is going on. I looked at /var/log/mythtv/mythbackend.log and don't see much there.

Running as a slave backend.

have you done any work with the ivtv drivers? most of the mce cards are not supported with the ivtv version shipped in R4V5.

Have you tried running the front end from a shell window to catch the ouput? This is a pretty common recommendation when the logs aren't helpful...

Where can I find some info on the exact tweaks that I need to make for my version of the MCE card?

I have not yet tried to launch the frontend from the console and watch the output. I will do that tonight when I get home.

Thanks for all the help.

you'll just have to search the forums for what you need as far as ivtv, it is spread all over the place, as far as I know there is not a definative guide to this version supports these chipsets and they are refrenced like so, you just have to go plugging in numbers and see what happens. and preferably have a newish driver.

Ok, did a search, tons on info. I will start messing around with IVTV tonight. What about my second question about mythweb. Has anyone seen the error messages that I put in my first post?

From your first post I see this is starting as a "slave" backend. Do you already have a "master" backend running? What are the ramifications of running a slave backend if there is no master? I haven't run a master/slave setup so I don't know the answer...

I only have 1 system right now. it is the backend and frontend. Where would I change it to a master backend rather than a slave?

Your one system is the master backend. You cannot have a slave w/o a master.

so any ideas why my mythweb says this when I try to load it

as you can see from my first post mythbackend IS running.

Are you running the same version of MythWeb as MythTV? That is about the only thing I can think of...

I Will check tonight. The version of mythweb that I am running is the one that was installed automatically by the auto-install. I will post results later tonight.

You may also want to check the MythTV archive. If you auto installed and did not install or compile any MythTV modules, then they should be the same.
