I had these problems here in the Ruhrgebiet/Düsseldorf region when the
frequency layout was changed in April. Somehow VDR did not get the changes
right, don't know if that was possible at all. Solution was to replace
channels.conf with the new one from VDR wiki.

The second line has no audio/video PIDs, so no audio/video reception.
The two lines have different service IDs - so they refer to different
services. The EIT table contains a field service_id, and VDR has to associate
the EPG info from that table to a channel with this service ID. If the EIT
for VOX refers to the service ID 2818, only the channels for the second line
will have EPG.
The PIDs are set from data in the PMT table.

If the pragmatical solution (new channels.conf) does not work, you might want
to analyze the relevant SI information:
Install dvbsnoop. For command line options, read their examples list.
Retrieve the PAT at PID 0x00.
Retrieve the PMT for VOX at the PID given by the PAT.
Read the EITs at PID 0x12 and find the one for VOX. Look at the service ID it
