[mythtv-users] Fastforward/Rewind Not working

Tue Jul 31 03:50:56 UTC 2007

Table recordedseek is used during fast forward/rewind during playback of 
recorded programs.  Apparently (I'm speculating on the details, here), 
Myth records "marks" in the recordseek table to guide it through the 
recording during non-standard playback.  Here's a sample of the 
recordseek table:

+--------+---------------------+------+------------+------+
| chanid | starttime           | mark | offset     | type |
+--------+---------------------+------+------------+------+
|   1009 | 2007-07-10 20:00:00 | 2447 | 1273985024 |    6 |
|   1009 | 2007-07-10 20:00:00 | 2448 | 1274517504 |    6 |
+--------+---------------------+------+------------+------+

I'm assuming the offset is frames.  Any way, I copied my recorded table 
to a new system (along with the recordings directory) and all worked 
except fast forward/rewind.  It all started working when I included the 
recordseek table.  You may have a corrupted recordseek table.
