 > Can you provide mythfrontend, mythbackend, and dmesg output for this
 problem?  Default verbosity should be fine for now, but please don't edit
 the logs, make them from backend and frontend startup-- so restart the
 backend and start capturing the log, restart the frontend, start livetv,
 and wait for the problem to happen.  Then get dmesg, and post all of the
 above here.

 Robert,

 I am not sure I know how to capture the dmesg output, can you give me an
 example of the command you need me to execute and I will do that.

 Also, I think I've learned more about this problem than when I initially
 reported it.  I believe what is going on is when watching live tv the
 stream is written to a file and it is actually the file that is being
 watched; at least that what I understand based upon reading the various
 threads.  Further, the problem seems to occur when the file is changed ie;
 when one show ends and another starts.  So, it is not just on the hour but
 also on the half hour if a show stops and another starts on the half hour.

 If the above is correct then I believe what is happening is some sort of
 delay while one file closes and another is opened.

 Last, the severity of the problem has become much less since I wrote th
 original ticket.  Now, rather than getting the error message "Error: Video
 frame buffering failed too many times." as the one program ends and
 another begins I just see a brief 1-2 second stutter in the display.  For
 example, live tv may pause for 1-2 seconds and then resume without any
 further issues until the next transition from one show to another.

 John
