New description:

 When entering LiveTV and sometimes when in LIveTV at the changeover point
 for the next show this error message is displayed.
 "Error was encountered while displaying video."

 Sometimes if you leave LiveTV mode and go back in it will start to work
 again, sometimes you have to do this 4 or 5 times. Sometimes it never
 seems to want to show LiveTV.

 The frontend longs suggest its some sort of issue with the ring buffer
 file being created :-

 Since scheduling a recording works fine (even the TV show you wanted to
 watch live) its clearly not an issue with physical disk space or a
 permissions thing. Both the frontend and backed are running as the same
 unprivileged user "mythtv".

 There is nothing of interest in the backend logs as far as I can tell
 related to this.

Comment:

 What revision were you using?

 There have been a number of fixes for this and related problems in the
 last 72 hours.

 Also I will need full backend and frontend logs with '-v
 record,channel,siparser' and '-v playback' respectively. If they are on
 seperate machines, sync the clocks. And use the latest SVN, and tell me
 the revision.

 Please use "Attach File" for the logs.
