We have had transient data issues where a national lineup was lost.
Also after the EPG maintenance updates in october announced here some internal IDs changed and the older IDs would give a 404 - see DVR EPG Maintenance
With regards to Kabel Deutschland lineups for your post code in Wedel, I see that Hamburg is only 20 km away whereas Schleswig-Holstein is about 100km
Any reason why you are not selecting lineup Kabel Deutschland Hamburg Digital instead of Kabel Deutschland Schleswig-Holstein Digital ?
And with regards to virtual channels, I am going to ping two fellow users who have been feeding back to me the issues with the Kabel Deutschland lineups which we have been addressing. Virtual channels did not come up as an issue. The only big issue with kabel Deutschland appears to be the overlap of radio and TV channels
