<br>You may have a problem I have just solved.<br><br>Mythweb goes and checks all the icons (thumbs) for the programs and<br>generates them if they are not there. It retries each operation for a<br>while if the mpg / nuv is invalid or absent.
<br><br>Look in /var/log/mythtv/mythbackend.log to see whats going on. I saw<br>lots of invalid files.<br><br>The reason was there were several nuvs with 0 file size created while I<br>was messing with the system during upgrade.
