#3058: losing 3-4 minutes at end of programs

     Type:  defect                  |      Status:  new    
 Priority:  minor                   |   Milestone:  unknown
Component:  mythtv                  |     Version:  0.20   
 Severity:  medium                  |  
 I'm running latest svn (12739), with frontend/backend running on primary
 machine (with one PVR350 tuner), with a secondary backend (with two PVR150
 tuners) saving recordings via nfs to primary backend server.  I have
 noticed that all programs recorded over this seem to end about 2-3 minutes
 prematurely, even though it shows length of program to be 29:57, or 59:57
 minutes. When I view the program and get to the point it's about 2-3
 minutes from the end of the program, the playback simply stops.  I'm not
 certain if recordings from the tuner on the primary box are having this
 issue at this point, but it seems that it is related to nfs, in that the
 remainder of the Ringbuffer doesn't get committed to the destination file
 properly.  I have the NFS rbuffer set at 8192, and have the wbuffer set to
 256.  The other result of this behavior is while watching livetv on the
 primary server from one of the tuners on the secondary backend, I get
 momentary pauses about every 1-2 seconds, unless I pause the program for a
 few moments, and then play with a timestretch setting at 0.9, preventing
 the player from reaching the end of the file being written to. I have
 tried various wbuffer settings up to 8192, and it simply seems to require
 a longer pause before playback. There is nothing notable in the log files.
