[mythtv-users] "Error opening jump program file" from Clientmachines with Live TV

Mon Sep 20 11:50:25 UTC 2010

Hi Jim

Thanks for your suggestions.  I run one attempt to connect to the backend
system using Live TV from the client machine and captured the relevant
section of both logs below.

The backend log is:

2010-09-20 20:36:55.182 UPnPautoconf() - No UPnP backends found
2010-09-20 20:36:55.199 No UPnP backends found

No UPnP backends found

Would you like to configure the database connection now? [no]  
[console is not interactive, using default 'no']

Error in my_thread_global_end(): 2 threads didn't exit

Although I know nothing about MythTv it looks as though I have the dreaded
SOCKET ERROR PROBLEM for which I am told there is no cure.
One thing I can't understand is the error - " Error: No valid capture cards
are defined in the database." Reported in the backend when there is a
functioning Divico Fusion HDTV DVB-T Plus card attached to the backend
machine working fine with Live TV if you logon directly to the backend
machine.  Both client machines will not run live TV although they previous
both work fine with this configuration before Shepherd.

Kind Regards

Watching "live tv" is in fact recording and playing back the same file. 
That is how you get the pause and rewind features.

Probably you need to research the issue a bit before you classify it as a
bug. Searching past posts on this list and posting questions here is a good
way to start that process. The developers are overworked and totally unpaid
so it stands to reason that they don't want everyone submitting bug reports
on every issue they encounter. You need to do the "due diligence" in proving
a bug exists and not just expect that the devs should spend their time
analyzing stacks of bug reports.

Have you checked the mythtv logs? Perhaps it is related to Shepherd EPG
software that you installed when it broke...

I would suggest a less demanding tone from you would get more assistance
from the good people on this list.

I don't know what the problem is and it's a lot of work to research it for
you without info on your setup, system and versions, troubleshooting steps
that you've taken, pertinent log entries, etc.

Try again with more info. The less emotional your post is the more likely
you will get help.

Good luck!
