No live TV on Remote Frontend

[dra2gonfly]

Earlier this week I finished off my first mythtv installation on the fedora 12 distro. I have both a backend and front end working very well with my 2250 tuner card. So then I decided to install the same fedora 12 installation on another box to use for my living room tv. After some time and headaches installing everything, I was able to get the frontend connecting to the backends database. But when I go to try to view live tv, or any recordings all i get after about 10 seconds is "error opening jump program file buffer". I have included both what I viewed from on the frontend and backend. After much reading and trial and error I still have no success. My two thoughts is maybe its trying to read recordings on the frontend(localhost) instead of the backend, or file permissions of some sort. Does anyone on here have any suggestions or possible other things that might cause this.
Thanks

Well after hours of trying, figured this one out. For some reason I never setup the host name on the box running the backend. So everything the front end was trying to grab was on hostname localhost which for the front end was itself, which was not the actual location of anything. Changed hostname on the backend server and ran the mythconverg_restore.pl and everthing was all good. One last step is to get the audio working over hdmi on my zotac mag hd, which i believe is a common problem so hopefully i can get that knocked out tomarrow.

Hhhmmmm... Spam much?

What do you mean by spam much???

[mattt]

Lol - I realised this might happen right after I posted it...

The post before mine was an obvious URL spam, but it was the first thread I'd browsed during last night's visit to the forum. After posting the spam reference, I noticed that similar messages had been posted in other threads, and would probably thus be dealt with by deletion - this has evidently now happened and left me looking somewhere between foolish and malicious

Sorry for any confusion caused

Cheers,
Mattt.
