Hi,

I have a problem for which I see a number of posts but none of them have resolved my issue. My experience level is that I've got one mythtv working, PVR-350 for TV in and out. The configuration of the problem system:

Intel Core2Duo
Asus P5VL2, Intel 945P Chipset
1G Memory
Chaintech GeForce 8500 nVidia Video Card
Hauppauge PVR-150
Fresh installation of KnoppMyth R5F27 (not an upgrade)
Using Tuner 1 with direct coax input, no set-top-box

Once I figured out how to get the nVidia video card () working everything seems to work except for Live TV. This system is currently set up as a frontend to another system I have. I can view previously recorded programs from that backend. Both systems are running R5F27.

I select Watch TV and immediately return to the menu. Searched for this symptom and found this page: http://www.knoppmythwiki.org/index.php? ... WatchingTV.
Went through all of the instructions, step-by-step:
- Confirmed cable and signal via direct TV connection
- Confirmed mythtv setup
- Confirmed that the PVR-150 is of tuner type 50.
- Toggled us-cable/us-cable-hrc/us-cable-irc, no effect
- Change capture resolution to 720x480
- Disabled VBI
- Powered off overnight to make sure it came up clean this morning.

Logs all look fine, no error messages that I can see. Here's the output suggested by http://www.knoppmythwiki.org/index.php? ... ngLogFiles

I'm stumped. Thanks in advance.

So I found this post: http://mysettopbox.tv/phpBB2/viewtopic. ... getentryat and followed it to this post: http://mysettopbox.tv/phpBB2/viewtopic.php?t=9424

Have run mythfilldatabase as user mythtv a number of times on my backend as well as fronend, can see the program lineup in setup and in 'Schedule Recordings' but still no Live TV. One note is that in R5F27 there isn't a tuner0 for the PVR-150 so I'm configured as /dev/video0 using Tuner 1.

Numbering of tuners and other inputs now starts at 1 for all drivers that conform to the v4l2 standards.

- Have you checked that there are no extraneous card/input definitions in your database as covered in the R5F27 hints?
- Have you checked that your input connections are correct? (I notice that you didn't mention them).
- Have you commented out the DVB driver loading in the /etc/init.d/KnoppMyth-tv init script?

- No extraneous card inputs. I've deleted and readded a few times.
- By input connections if you mean in mythtv-setup, yes. The only input configured is Tuner 1 and it points to my one Video Source, which seems to have all of the programming information.
J- ust removed the dvb driver loading, rebooted. Didn't help. Still same error messages in /var/log/mythtv/mythfrontend.log:

Other thoughts?[/quote]

At a guess either your backend isn't running or you messed up the hostname or network configuration and the one it's trying to connect to is not the one that the machine is using.

Solved. Thank you. It was a backend/frontend configuration problem. I now have two tuners, both of which work, including Live TV. I appreciate the help.
