One DVB-T channel not found

[phil78]

My NPVR (5.0.9.201026) gets only 5 of 6 DVB-T multiplex in France Paris area.
It doesn't find multiplex R2 on channel 25 (506 MHz). The tuner scan log file looks like it sees the multiplex but il's unable to read the informations included (5 channels : C8, GULLI, BFM TV, CSTAR and GULLI).
My other TV application Poutchin TV, using the same tuners, works fine with this multiplex.
Also TSReader Lite reads this multiplex fine.
Increase the scandroptime parameter in config.xml has no effect.
NPVR log files and TSReader Lite HTML file are attached.
Could someone help me to solve this issue ?

NPVR log files and TSReader Lite HTML file are attached.

Sadly, the forum software silently ignores attachments that are bigger than 2 Meg.

I took a look at your link, but unfortunately the logs missing the most important bits.

Can you rescan, and post the NextPVR logs? (the zip file with all the files)

Hard to know, since we didn't see the scan where it failed. Could be something like marginal frequency on that channel. Glad to hear you got the channel now though.

It does look like maybe you have reception issues on that frequency.

Why does it work fine with Poutchin TV and TS Reader Lite with the same tuners ?

I don't know. The signal levels reported by the device look like it's sometimes good on that frequency, and sometimes not.
