-------------------------------------------------+-------------------------
 I am using Comcast in Massachusetts. I have had this problem with two set
 top boxes: first a Cisco RNG-150, then I exchanged it for a Scientific
 Atlanta 3250 and the problem continued. The firewire card in the computer
 is " BYTECC Firewire 1394A 3+1 Ports PCI Card - VIA Chipset Model BT-
 FW310V"

 Sometimes during a recording the recording stops and messages appear in
 the log as follows (see below). These messages continue until the end of
 the recording time, filling many megabytes of log, and no further video is
 recorded. I have tried with the reset bus option selected or unselected.
 That makes no difference. I elected finally to leave reset bus unselected,
 because the reset bus was disabling the plugctl setting
 "oPCR[0].n_p2p_connections=1".

 The problem most often occurs within one minute of the start of a
 recording, but sometimes it happens during a recording. It happens some
 days with every recording, and some days it does not happen at all.

 My workaround is to restart the backend as soon as this happens. I have a
 script that scans the log and once these warnings get to 300 msec, the
 script restarts the backend. This works and after the backend is
 restarted, recording resumes in a new file and the program is recorded
 successfully. This has some disadvantages: the recording is split into two
 files and any other recordings on other tuners at the same time are also
 split into two files.

 I would like to suggest that the firewire recorder be changed so that if
 these messages occur, once it gets to 300 msec, it closes the firewire and
 reopens it (performing similar operations as killing the backend, but
 without interrupting other recordings and without starting a new recording
 file).
