Can anyone help me, please?!

I had the exact same problem 2 days ago. I had no TV or TV preview working, I kept getting "Unknown Error"
It turned out that my MySQL database had got corrupted. I "dropped the schema" and it was recreated and i was back in business. I lost all scheduled recordings and TV channel information though so it was major pain in the butt.
I have now exported my channels so if it happens again, I just re-import them.

Good luck,

Try to repair the database like described here (german thread, but the pictures speak for them self or try (googel) translator).

 

[LemonDeaf45]

I had the same problem and the DB repair worked, I needed to rescan the channels as well, Thanks.

UPDATE:
Just wanted to insert this more up-to-date link, in case someone else find this links at the top of their search results:

http://wiki.team-mediaportal.com/1_MEDIAPORTAL_1/16_Support/Troubleshooting/TV/Repairing_database_(MySQL)

That did the trick for me. The German link above is no longer relevant - broken images, tool link broken - and the above link is easier to follow, anyway

(but appreciate the info being posted, of course, Der_Bub)


(the real trick would be for MP to detect such corruption itself, or if there are no negative consequences, run the repair command on a schedule, just in case. May be a MP2 thing. I'm just seeing if MP is going to be my replacement for WMC.)
