Hi, i think it works. Deleting all channels, doing a new scann, arranging my favorites and hopping from tele5 to prosieben an vice versa no crash.

Btw. i´m missing in scann 1 or two filters:

1.) "only open channels"
2.) "only TV".

Regards

Looks like EPG base was damaged. Possible remove only epg files.
