I have a backend with a prv-500 on which I can watch live tv and previously recorded tv. I have built a frontend that is looking at this backend and can watch live tv from the backend and shows the recordings on the backend. It even shows and plays the thumbnail view when selecting a recording but when you select one to watch you are instantly returned to the frontend. Obviously the remote frontend is connecting to the backend as I can see the recording play in the thumbnail but cannot play it. I have checked every logfile in the /var/log tree and there is nothing that corresponds. Is there another place I should be looking for log files? This frontend was a full autoinstall with the backend and mysql shutdown. I had the same issue with a frontend running from the cd on a different computer so I'm guessing that I have something configured wrong on the backend. The line about skip networking has been remed on the backend and mysql restarted.

On the frontend, look for logs in /home/mythtv/.xsession-errors .

We backed off from R5B7, and also didn't do the restore from my old server and that seems to have solved the problem. I think there was something in the restore that was causing issues.
Thanks for the reply.

I am having the same problem! My frontend computer is also a backend however. I started mythfrontend from an xterm and here is some of the output:

"Watch Live TV" does not work either. I am running R5D1 on both computers. I have searched for "RingBuffer Failed to open remote file" and " RemoteFile::openSocket(control socket)"
The most relevent threads are this one and : http://mysettopbox.tv/phpBB2/viewtopic. ... rol+socket
I deleted the Twinhan 102G card in myth-setup, the only capture card in this computer, but that did not help.
My "frontend" computer is configured:
e-machines 2895
Intel Celeron 2.8 GHz
512 MB ram
120GB hd
MB: MSI MS 6714
845GV chipset
Onboard video
Twinhan 102G DVB-S
Anyone have any suggestions?
Thanks,
Derek

What strikes me as strange is the part here:
Could not connect to server "" @ port -1
Are you able to view the list of recordings on the backend server from the front end?

borgednow, yes, I was able to see the recordings, and the preview would even play in the small window. I have since installed another distro, but I should be able to duplicate the errors with the frontend running off of the cd.
I don't know if it is related or not, but the CD-RW and DVD drives would not automount. I did not try to mount them manually, as I had forgotten about it.
I also tried conecting to the MBE with the other distro. Unfortunately, the other distro I installed is running Myth 0.20, and I get the version conflict error.
If there are any troubleshooting steps I can do, please let me know as I will eventually be re-installing Knoppmyth. And it may happen no matter what distro I use.

The only thing that comes to mind is I keep seeing people having similar types of problems and getting it to work after they update their video card driver on the front end.
I could be wrong on thinking I see that, as it doesn't really make sense to me that that would be the problem, but it might not hurt to check.
Of course, I think most of them were running an ati video card.
What brand video card do you have in your front end box? Yes, I know it has nothing to do with the error messages, but I'm stumped on those.
edit: Nm, I see you posted that you're running onboard video. I don't know if one of those chips you listed happened to be the video chip, but you might want to check if it's made by ATI.
I know, it's unlikely to be the cause.

I was having the exact same problem with my frontend (Could not connect to server "" @ port -1).
I ended up mounting the backend's /myth to the frontend and I was able to finally view the recordings. Should you have to do this?

I forgot to update the hostname with the IP address of my BE under utilites->setup->general. Now it works great.

Well, I was able to get the front end box working when I booted with the live CD. All I had to do was: (from The Pamphlet of Knoppmyth)
Quote: Edit /etc/mysql/my.cnf, comment out 'skip-networking'. The backend will only accept the mythtv user with a password of mythtv.
Before:
skip-networking
After
# skip-networking
Restart MySQL(as root)
# /etc/init.d/mysql restart And it worked. I had already done: (from http://mythtv.org/docs/mythtv-HOWTO-6.html#ss6.4) Quote: $ mysql -u root mythconverg
mysql> grant all on mythconverg.* to mythtv@"192.168.0.%" identified by "mythtv";
mysql> flush privileges;
So I reloaded Knoppmyth to the hard drive, and kept my fingers crossed. But the same error occured. So I installed the Intel driver for the 845GV integrated video. I discoverd that, besides having shared memory, the graphics reside on the PCI bus. I don't know if that is relevent or not. Still the same error.
So I killed mythbackend running on the front end machine. Nothing.
Next I mounted an MPG4 DVD and played some video from it. The video played fine, no errors.
Next, I will load a TV card in the frontend only machine and test if the video from it can be played. I will also tripple check the IP settings, maybe there is a typo.
I will also try installing an old PCI video card, to see if that helps. I'll post my results.
I don't really know where to look after that. If the LiveCD works, there must be a way of getting it to run with Knoppmyth installed to the hard drive. What could be different between the two?

I installed a TV tuner card on the frontend machine, and it worked OK. I have upgraded the frontend to 0.20, and left the tuner card installed. The only thing I know to try is to upgrade the MBE to 0.20, but I am a little leary about doing that just yet. Anyway, I have all but given up on 0.19.

FYI,
I ran into the following issues when I was attempting to get a frontend-only system working:
HP ZE4145 MythTV Worklog
11/22
Did an auto-install of KnoppMyth R5D1 on laptop
Setup IP address of myth backend (192.168.0.50) as database, with same user/password as backend
11/23
Could view all recordings in the "View recordings" screen, thumbnails would not appear, videos would not play
Configured the frontend "Utils/Options" screen to look at the backend IP address
Could view all recordings in the "View recordings" screen, thumbnails would play, but the actual video would not
Used the wiki page: http://knoppmythwiki.org/index.php?page ... nlyInstall
to stop the mythbackend on the laptop, which allowed video to play
/etc/init.d/mythtv-backend stop
