Something that you can try is to use the OFDM synchronization block from
gr-isdbt.
https://github.com/git-artes/gr-isdbt
Just replace the gr-dvbt ofdm_sym_acquisition block with the one from
gr-isdbt. Leave the freq. error output unconnected.
I believe German DVB-T is 16QAM 2/3 rate, so your captured signal should
be at least 12 dB to 15 dB above the noise, preferably more.
Also, since you're using a B210, you can use the correct DVB-T sample
rate of (8,000,000 * 8) / 7 Msps (instead of 10 Msps) and delete the
rational resampler block in the flow graph.

Hello all,
I am trying to receive a DVB-T signal which I have recorded using a USRP
B210.I have set all parameters correctly but I am unable to receive the
output stream. I already verified that I have a spike at 746MHz which is
the frequency of my broadcast station.i think the problem is with the
synchronization. I am getting restart aquisition as my grc output
continously. There are some messages before as well which I have attached
as a screenshot. Anyone who could check where the error is? Thanks all
very much.
Regards
Ahsan
