[QUOTE="CHli, post: 516767, member: 13587"] Did you try : global => dvbc symbolrate 6875 ? If you don't find anything there then edit the xml file and search/replace the qam setting to the approriate one. Mod64Qam or Mod256Qam (I did not check what is configured in the files) As a quick theory you have these differents settings affecting the scanning results : [list]Frequency of the transponder : (between ~50MH-~850MHz), what I don't know is if there is a list of commonly used transponder frequencies (If it's define in the standard or if it's up to the provider to decide where they want to have their channel)[/list] [list]QAM settings : (the number of possible values per / symbol) E.G. QAM 256 = 2^8 => 8 bits per symbol, the higher the value the better the signal needs to be to receive error free streams.[/list] [list]Symbol Rate : numbers of symbols per second. (tied to the channel bandwidth)[/list] [/QUOTE]
