    it seems w-scan have problems in retrieving list of services for dvbs2 frequencies. I change the frequency to other dvbs2 that has 8PSK modulation and result was no list of services. I tested same frequencies with "scan-s2" program that is a dvb search program same as "w_scan" but with some less facilities. It didn't face with a problem in retrieving information. i also foung that this function in descriptor.c maybe need a new look at it! ;-) I will try to find the problem in code (if any) and report it. here is the functions:

    void parse_S2_satellite_delivery_system_descriptor(const unsigned char *buf, void * dummy) {
    hd(buf);
    /* FIXME: finding that descriptor means that we're dealing with two
    * transponders on the same freq. I'm not shure now what to do this case.

    I think it is not because of broken NIT but on the other hand I try to communicate with service provider and report this issue to be sure the problem is not in their Ts packet and Broken Service Tables.


    Best

    Thanks for the answer! Before reporting the bug to the satellite provider I want to be sure there is no way to survive this fault in NIT.
    In Set-top boxes there is no problem with searching and receiving this frequency and transponder. It also has no problem when streaming whole frequency transponder to network by MUMUDVBstreaming software.
    Maybe I don't have enough information about what happen when tuning the frequency and retrieving information from NIT or other stuffs in TS packets. :P By the way, what is the difference here and is there any way to survive this fault?


    another thing is that as i mention in the first post the program have retrieved channels(services) names and list them but didn dump any of them:

    When I use just one line in inital tuning file w_scan can not even lock the frequency! I should Write same line twice! :(
    In log we can see symbol rate of 29900 has changed to 27500 by w_scan and it seems buggy !
    Any help will be appreciated.
    Thanks

    When I use just one line in inital tuning file w_scan can not even lock the frequency! I should Write same line twice! :(
    In log we can see symbol rate of 29900 has changed to 27500 by w_scan and it seems buggy !
    Any help will be appreciated.
    Thanks
