Good day, there is a compatibility issue mediaportal and my satellite equipment. I use "dvbworld dvb-s2 2104 usb" with the latest bda-drivers on windows 7 x64 with all service-packs and updates. Circular LNB connected without DiSEqC and is aimed at 36e. I can not scan transponders with circular-L polarisation. Not be scanned for example 12073000/8PSK, can not scan 12341000/QPSK. Although these transponders are scanned perfectly in other programs - ProgDVB, DVBDream. I'd like to use mediaportal with my HTPC, please help.

Sorry for my English.

    Did you change anything in configuration files with tuning details used for channel scan?

    In addition please provide screenshot of your satelite settings from TVServer config

    I apologize for the inaccurate log. Gathering information today late at night.

    The fact that I was trying to catch a signal from this transponder at different values of the polarisation, different values of the lof-1. Yes, the list of transponders manually changed, but only to reduce the scan time. Here is a complete log with options scan.

    Even though I already tried to adjust the transponder list and scan the list. I updated transponder list by pressing "Update satelite list". All correct download. Scanning Eutelsat W4, W7 and post the log scan.

    Well, a very strange results. But the transponder 12073, 12265, 12341, 12380, 12456 i can't scan, although some CircularL transponders can be scanned.

    are all the transponders you are having problems with above 12000 ?
    It sounds like the LNB settings HI/LO/Switch are wrong

    Code:
    2010-10-27 22:59:41.318859 [(6)]: LNB low:10750 hi:0 switch:0
    but I believe for circular this should be 11250

    No, I successfully scan the transponders 12399_R, 12437_R, 12322_R, 12245_R and 12476_L! I select Ku-circular In the band section. Tell me how else I can scan the transponders are not available, I'll do. Perhaps the tab General -> Scan can change anything? It looks like this.

    p.s. About not correct HI / LO / Switch ..
    Maybe you're right. Because scanning 11823_8psk my card issues barely audible high frequency noise (this was the date of purchase), and when trying to crawl 12073_8psk there is no noise. Most likely you are right, but what settings to use in this case and how to check?
