Thread: AlJazeera pid

Clipped the following a few months ago and cannot locate the thread
The following are supposedly instructions to enter AlJazeera into my DM500s, have followed them but with no luck
Quote ; In manuel transponder scan enter the Freq ect then press yellow button to enter pids. Press the red button to change Dec to Hex then input pids
Vpid 1121, Apid 1122, pid1121, tick no DVB and hold name
Press yellow to test (you should have pics) if you have pics press exit then Blue button to save, exit to channel list and go to All Services and find the new service that is flagged as unnamed service, this should be AJZ just name and add to favourites if you wish, End Quote

Thanks to who ever wrote this but when i get to push yellow button to test my pics i get a blank screen
Do i have to enter a specific Frequency and Symbol Rate or should they be covered by the general scan i did at set up
If i mange this should i be able to pick up Central 7 and a few other channels i don't presently have
regards Allover
