I believe my issue resolved, got Mandingo on the IRC who assisted tremendously yesterday.
I tested last night, with my pvr-500 card and the hvr-1600 (2) and they all worked well, did not get any duplicates even after a router reload, a full reload and full regen, nor when you get the prompt that mythtv is ready - all instances were the duplicate use to return - this is even after choosing option yes for the 1600's and the 500 on the orbiter to be configured. What I got for the machine with the 1600's, was that the input was set to a value that does not exist when exiting mytht-setup, but I had not added any videosource to the respective cards; would not be using the digital portion of the 1600's, in my portion of the Caribbean we still broadcast anolog.
It was simple, changing the Device Template (DT) for the 500 card and the 150, to remove automatic configuration, will post some screen shots (or the exact column) when I reach home tonight; unfortunately have to be in office for the day.
For the hvr-1600 simple changing the DT, the portion where it say (you would see the INSERT
first in the small window)
INSERT INTO `capturecard`(videodevice,cardtype,defaultinput,hostname) VALUES ('/dev/video0','MPEG', 'Tuner 1', '<%=HOST%>'),('/dev/video1','MPEG', 'Tuner 1', '<%=HOST%>');
INSERT INTO `capturecard`(videodevice,cardtype,defaultinput,hostname) VALUES ('/dev/dvb/adapter0/frontend0','DVB','DVBInput', '<%=HOST%>'), ('/dev/video0','MPEG', 'Tuner 1', '<%=HOST%>');
Thanks again; have to finish building out MD's ensure all is working and make my wife happy again.
