Comment (by angela.schmid@…):

 I identified/solved my problem. Starting with 0.27-pre, recordseek is
 written every 10 seconds, previously it was written at the end of the
 I noticed that some tables were using the InnoDB engine. I changed them to
 MYISAM and afterwards everything is fine.
 Even changing the volume produced hick ups, as it writes the volume change
 immediately into the settings table. Pressing the remote constantly halted
 playback until released.

 As MythTV only supports MYISAM, I still tried the following MySQL setting
 and everything was also OK:
 innodb_flush_log_at_trx_commit = 0

 Performance information using the MySQL setting:
