To use Vbox multirecord available from mythtv 29, you need to rescan 
(using mythtv-setup) VBox channels, this will create the appropriate 
data in the dtv_multiplex table of mythconverg database. The required 
data is extracted from VBox data when channel scanning is done (using a 
Vbox api call). The normal Vbox playback URLs do not contain this data
