[mythtv-users] Downgrade from 0.20 to 0.18.1, missing field dvb_dmx_buf_size

[Wilhelm Meier]

Hi,

since I have problems to get 0.20 with my dvb-s nexus-s running, I wanted to 
downgrade to 0.18.1.

I had the old 0.18.1 packages archived and did a database backup. So I 
installed the old packagesand dropped the database and recreated it with the 
backup.

When I now start mythbackend I get in the backend-log:

DB Error (getdevices):
Query was:
SELECT 
videodevice,vbidevice,audiodevice,audioratelimit,defaultinput,cardtype,dvb_hw_decoder, 
dvb_recordts,dvb_wait_for_seqstart,dvb_dmx_buf_size,dvb_pkt_buf_size, 
skipbtaudio, dvb_on_demand,firewire_port, firewire_node, 
firewire_speed,firewire_model, firewire_connection FROM capturecard WHERE 
cardid = 8 ;
Driver error was [2/1054]:
QMYSQL3: Unable to execute query
Database error was:
Unknown column 'dvb_dmx_buf_size' in 'field list'

The field dvb_dmx_buf_size is not in the backup!

Help appreciated!
