Hi i made a fresh install when moving from win mediacenter to mediaportal and now my firedtv cant find any channels ;o neither the firedtv viewer nor mediaportal finds anything... they both says the dignal quality is ok tho. im not sure of were to look anymore so any tip would be handy ;x all the tvserver errorlog says is ;

now ive tried a new install on both vista and xp and followed the comhem settings manual found in the wiki and i cant get it to work, the dvbfix is installed aswell. im not sure if it has to do with the 1.1 alpha mediaportal cus i got it working some time before on the previous version.
ty in advance
