Hi,
I wanted to do a fresh install of MP so I downloaded 1.17.0.
I can't get the scan to find any channels. I've tried with a parallell program FireDTV Viewer( as I have that card of the type DVB-C) and it finds
the channels after a "full scan". I've tried to find the equivalence in MP 1.17.0 but did not find it.
I've tried all the enclosed transponder lists for Sweden with no signal and no channels found. I found scanning parameters on my provider's site
and thought to try the advanced tuning options. The feedback doesn't even state "No signal" then, just:

Scan freq:306000 Mod256Qam symbolrate6875....
Scan done, found 0 transponders....


"Search for transponder list" was checked.
I'm enclosing log files. I would appreciate any help. Thanks!

Still trying...
I tried 1.16.0 so it seems not to be the MP version, rather some setting in my win7.
Uninstalled (complete) and reinstalled 1.17.0.
I tried with security settings by letting all MP folders become writable....to no avail.

Ok, it's been 15 days. No support for this? Please let me know if I'm in the wrong place or I have missed any essentials for support.

    Hello

    First, sorry for the delayed response - don't know how I missed seeing your thread. :oops:

    I'll get straight to the point. The problem is this:
    [collapse]
    [2017-08-01 16:00:35,085] [Log ] [44 ] [INFO ] - dvb: Add Mediaportal TsWriter filter

    at TvLibrary.Implementations.DVB.TvCardDVBC.BuildGraph()[/collapse]

    In other words: some of TV Server's vital components were not installed correctly. That might be because certain pre-requisites are missing, I don't know... but usually the MP installer ensures all pre-requisites are installed. :confused:

    Please try to uninstall and reinstall MP 1.17.
    Make sure you run the installer with administrative privileges (right click -> run as administrator).

    Regards,
    mm
    P.S. This problem is not related to your tuner or firewall.

    Thanks for noticing my post ;)
    I have reinstalled 1.17.0 with the same result I'm afraid (as administrator).
    I've reinstalled my win7 OS so it should be pure as a baby.
    So, last time TV was working for me was 1.13. I installed that version and scanning worked.
    I then installed 1.17, checking "update" on installation. Again no scanning. What's been added, I wonder?
    Logs included.

    AFAIK, only dependency on the Visual C++ 2015 redistributable.

    Perhaps your installation of that component is somehow broken/corrupted. That would explain why MP's installer would think everything is okay.

    So, try uninstalling and reinstalling the Visual C++ 2015 redist.
    You need the 32 bit (x86) version for MediaPortal.
    Get the latest version here:
    Download Microsoft Visual C++ 2015 Redistributable Update 3 from Official Microsoft Download Center

    If that doesn't work, try the Visual C++ 2013 and 2010 redists. Always 32 bit versions.

    Progress! I reinstalled C++ 2015 and MP 1.17 and now it scans and finds channels. I use a CAM card and it seems that is not recognised as it says "Channel is scrambled" when trying to watch those channels. I know they worked when I tried 1.13 a little while ago. Should I reinstall the C++ 2013 and 2010 too?
