Comment (by mdean):

 Please take all the discussion and "me too" posts to the users mailing
 list.  This ticket is already long enough that it will be hard for
 developers to find the important/relevant information in the 30 comments.

 The generic error message, "Error opening jump program file buffer,"
 describes the final symptom of many different problems--the file MythTV is
 supposed to play back in Live TV doesn't exist.  This problem can be
 caused by system or MythTV misconfiguration or, in some cases, MythTV code

 Therefore, it is quite possible some of these "me too" posts are actually
 seeing different problems (such as having incorrect file system
 permissions, using NFS without disabling file system attribute caching,
 having incorrect times on frontend or backend systems, having
 misconfigured Input Connections, or many other problems with the
 underlying system) and can fix their configurations.  This applies
 especially to those who have only NTSC (SDTV) channels and a single tuner
 (because, obviously, they cannot have a case where they switch from SDTV
 to HDTV channels).

 Until we know it's a MythTV code failure, discussion should occur on list.
 And, even once we find it's a MythTV code failure, we need to identify
 whether it's the same issue that was reported here or if it needs its own
 ticket.  And, if you are not seeing the same issue as the original
 reporter, posting to this ticket is not going to help you get your issue
 fixed (as you won't get instructions on how to fix system misconfiguration
 here and the developer who fixes this issue will be focused on the
 originally reported issue).

 In other words, having the message, "Error opening jump program file
 buffer," in your logs messages does /not/ mean you are seeing the same
 issue as the original reporter.
