So it seems as if importing a channellist xml from the alpha build screws up something in regards to being able to se the channels on the client.

Can anyone else confirm this or have you guys successfully imported a channellist exported from the alpha build?

    same here. I've imported a channellist.xml from 1.0.2 release. No EPG, no Channelgroups and no records on the clients.

    This is a major showstopper for me. I have channels from 4 sattelites and channels from mycable company that i have spend many hours sorting and putting into channelgroups :(

    Hopefully this can be fixed ASAP




    I found a temporary workaround.

    I scanned 1 satellite and found that those channels were showing up on my clients. I then put a few channels into a test channel group. that showed up as well on the clients.

    Then i deleted all the scanned channels (except the test channel group) not to get duplicate when importing my correct channel list. I then imported my own lost and its all there now. Then i deleted the test group.

    If im not mistaken this problem must have been reintroduced from a previous bug? im almost certain i ran into this bug a while back

    I have the same problem and the same exception, but I didn't import anything, I scanned channels in SetupTV (IPTV). Channels are working in SetupTV preview, but not from MediaPotal

    I've the same problem. When importing channels from 1.0.2 , no channels are visible in Mediaportal and
    TVguide is not working (no channels, strange texts etc)

    I've also tried using the plugin BackupSettings to import TV channels, but this showns the same problem.

    Same problem here. In tvguide of mediaportal see text "label missing". Don't know what that means.

    Hope that the problem will solved soon.

    Hi all,

    I did a rescan of all the scannels and the problam was solved for me.

    I think you mus't import the channels, but do a new scan.

    Hope this will solve the problem for you all also.

    I think this is no bug, maybe the Database has changed.

    When you import the channels und do a rescan everything is working:)
