[mythtv-users] [SOLVED] FF/RR and jump ahead/back gone all wonky

mythcommflag --rebuild resulted in lots of messages like:

DB Error (position map insert):
Query was:
INSERT INTO recordedmarkup (chanid, starttime, mark, type, offset) values (
'1004', '20050113205900', 7305, 6, "2371883046");
Driver error was [2/1016]:
QMYSQL3: Unable to execute query
Database error was:
Can't open file: 'recordedmarkup.MYD'. (errno: 145)

I did:

bash> mysql -p mythconverg

mysql> repair table recordedmarkup;

Then re-ran 'mythcommflag --rebuild' and the FF/RR problem was fixed.

Thanks,
mjc
