I have just upgraded my XBMC installation to the latest from svn. My version is: XBMC PRE-10.5 r35575. I run Ubuntu 10.10.

Now the playback of recorded programs from my mythtv backend does not work anymore. Is there a protocol problem? I run an ancient Mythtv installation (version 20).

I can browse the content of the myth box from my XBMC without problem, including thumbnails for each film, but when I try to play it, nothing happens.

In the xbmc.log I get the following:

I have sniffed the network traffic and confirmed that the XBMC box is talking to the Mythtv box on port 6543, but I have no clue what goes wrong.

With my previous installation of XBMC whichh was the precompiled version for Ubuntu 10.10 I did not have this problem.

I checked the updates made on the libcmyth recently and stepped back to revision 35199 for libcmyth. That fixed the problem.

The change made in revision 35200 according to the log is:
Code:
Added: #10650. Lookup the IP address of the host to be used for myth:// playback using the Myth Protocol QUERY_SETTING command. This removes the need to have the MythTV master or slave backend hostnames resolvable on the XBMC machine.

Apparently that fix does not work against a mythbackend of version 20.

Myth 0.20 was released on 11th September 2006. File a trac ticket if you really want to stay on a release that is over 4 years old.
Use MythTV for recording TV? Try the integrated MythTV support in XBMC Media Center. Now with commercial skip support built-in and integration with the Movie database!
