    I have completely reinstalled my MediaCenter.
    Windows 7, Terratec S7, Motherboard Asrock H77M

    I have scanned the channels and there were no problems finding them, but I get nothing but a black screen no matter what channel I choose. There are no error messages at all, just black screen.
    I have tried a remote client too - same problem.

    If I look at TV streams on the TV server configuration, I can see that it is actually streaming, so there is fine connection.

    I started out with the standard codecs from windows, then I downloaded the LAV filters and enabled the for TV - no change.

    I have probably forgotten a setting somewhere, but I can't find it. (Same problem on TV-server configuration/preview)

    Firewall settiings perhaps?

    Suggest posting logs.

    Had same myself couple of days ago after machine totally killed itself & had to reinstall OS & MePe - lost sound on system (due to vendor driver update I think) and no sound meant no picture on TV, but stream & EPG perfect as expected - does everything else work as expected?

    Cheers - J.

    Firewall was configured during setup so I can't imagine it is the problem. An other odd thing is that I know the remote client received the stream because the graphicscard fan started making loads of noice until I stopped the stream.

    I don't know if rest of MP is working - TV is my first test on the new setup.

    Will start scanning my movie library to see if I can see videos.

    Logs - yes of cause forgot. Will update with logs

    Ah - I always leave TV until last as it requires extra things to work over and above the basics - if you've tinkered with anything other than MePo, would suggest checking video playback outside of MePo, so fingers don't get pointed too soon in the game:)

    So it looks like database problem affecting stream.... from tvserver_tv log

    Hi,

    do you have vlc player installed on your HTPC or desktop PC? ? if so, start timeshifting manually inside the TV config -> Manual control -> start timeshift.
    If you see that the timeshifting has started, open the vlc player and open the stream rtsp://localhost/stream2.0 if you see a picture, then the timeshifting works properly. Please also take a look inside the timeshift folder you entered and watch out if there will be *.ts files created.

    hmmm... haven't done anything special with the MySQL. Assumed MP installer did the required?
    Now I probably messed further up because I changed computer name. Will this affect the MySQL database?

    sure, because in mp config - tv plugin you need to type in the hostname of your tv server pc (even if it is the same pc)

    I have now tried to do a recording. A .ts file is created and I tried to play it via VLC. Black screen!
    I have also checked the timeshift file - it is created. Have not tried to play it - I figure it will be same problem as recording.

    (renaming the mediacenter is in place - database and clients adjusted acordingly)

    Also, I have tried to play a DVD - it works perfectly.
    And I have tried this on the TVDB:
    CD C:\Program Files\MySQL\MySQL Server 5.1\bin
    mysqlcheck mptvdb --auto-repair -e -u root -p
    Everything gets status OK

    EPG is also working fine

    I have an other odd thing.
    When trying to copy a file into C:\Program Files\MySQL\MySQL Server 5.1\bin Windows says I need administrator rights to do it???
    There is only one user created on the system and is of cause an administrator - why can't I write a file???

    Can my problem have something to do with access rights?
