1.32 TV channel scan is not working (3 Viewers)

[horned_reaper]

With my new hardware, Windows 11 and MP 1.32 the TV channel scan is not working anymore. The frequencies are scanned but no channels are found.

It used to be working with the same TV card with my previous hardware and Windows 10.
Watching previously found TV channels works fine. I took over the MP TV Server database from my previous system.
It's the same with MP 1.32 x86 and x64.

Does anyone have an idea how to fix this issue?

It seems you have no signal.
Is your antenna plugged and/or signal OK (check elsewhere like in your TV set).
Also, try with MP 1.31 instead of 1.32.

Hello framug,

thanks for your reply.

Without the antenna plugged in, watching existing TV channels wouldn't work but it does.
I'll install MP 1.31 and let you know if it works.

Are you sure it's DVB-C channels and not IPTV ?
One of my cards is the same as you but I use it with DVB-T instead of DVB-C.
I can tell you that without antenna plugged in, no channel is displayed...

 

[horned_reaper]

Sure. I don't use IPTV at all.

Can you try manual scan (by using 'Advanced Tuning Options')?
Try this params: fq:410000 sr:6900000(not 6900!) qm:64 or 256

Or edit your "Germany.Full.xml" file by replacing symbolrate 6900 by 6900000.

 

[horned_reaper]

Thanks for your reply.
You're great!

The symbol rate field is limited to four characters:

With this XML file it works!

<?xml version="1.0" encoding="utf-8"?>
<ArrayOfDVBCTuning xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">

    <Frequency>410000</Frequency>

    <SymbolRate>6900000</SymbolRate>
  </DVBCTuning>

    <ModulationType>Mod256Qam</ModulationType>
    <SymbolRate>6900000</SymbolRate>
  </DVBCTuning> 
</ArrayOfDVBCTuning>

Has there been any recent related TV Server change?
Are there new scan parameter files?

Oh, sorry. I didn't know that.

Nope, there are no changes related to tune/scanning system.
And it looks like you are not the only one who has exactly the same problem (check this thread).
Maybe the problem is related to the "Hauppauge WinTV" products (requires exact symbolrate value - not in kSymbols).

 

[horned_reaper]

Interesting!
Considering the large amount of Hauppauge WinTV users, in my opinon it wourld make sense for MediaPortal to adapt this pecularity.

Can you try this one ?
Please stop TVService and backup before.
