This report might be of help to other desparate souls !!!!
I have just succeeded to install and activate my HDPVR P2 as primary in the lounge and with DSD 1131 as secondary in my bedroom connected with a 15m LNB line and a 15 heartbeat line using the intallation 2A on page 13 and the LNB configuration on page 29
With the HDPVR2P there was a bit of a struggle (90 min on the phone) to activate it and just about when the DSTV technicians gave up and insisted that I get a accredited installer, I pressed the scan button in desparation (which was not mentioned by anyone) and VOILA everything worked.
Then I installed the DSD 1131, using the EXACT setting as prescribed in the manual V3.1 on internet and phoned DSTV to have it activated. .... Disaster !!!! I was informed that the DSD was never sold by Game AND that the serial number did not correspond to the Smartcard number. It was suggested that I return DSD to Game (200km from my home) and demand a replacement. What now ???
I decided this did not make sense, I re-installed all the connections and checked that the settings were correct and called the Xtraview technicians again (not mentioning the previous episode). After enquiring about my settings, the techy instructed me to change the primary communication Port to "IN" and the secondary Port to "OUT". No luck nothing worked and I was instructed to get a proper accredited installer to redo the job.... that means R500-R1000 down the drain !!
I then decided to change every setting back to the settings prescribed in the V3.1 manual, switch of the power, let it cool, had a drink and booted up both decoders and gues what !!! the DSD did a proper scan and voila ... everyting worked
Bottomline !!!! USE the prescribed instructions in the manual and DONT let the techy convince you otherwise.
