[solved] Channelscan of UnityMedia (DVB/c) doesn't find all channels. (1 Viewer)

[Helios61]

Hi,
after some frequency changes unitymedia made last days (113 MHz -> 114 MHz, 121 MHz -> 122 MHz, 129 MHz -> 130 MHz) a new channelscan doesn't find all channels (for example arteHD, WDR Duisburg). If i import a channellist and edit the tuningdetails of these channels, it is working fine, but a channelscan (full and UnityMedia NRW) doesn't find the changed channels. Tested with DVBSky T982 and Digital Devices Cine CT2.

Best regards
Helios

Sorry, just not really sure what your aim is.
If you want help, can you please explain what you want help with, and post full log files.

@Helios61
i guess, if you have the information about changed/updated frequencies in your region, then you can create/update tuning xml file for it.
What XML file have you selected for scan?

@mm1352000 is there any possibility to use blind scan function available for some tuners?

Yes and no.

Yes, some tuner hardware and/or drivers support blind scan.

No, blind scan is not supported by the MS BDA as far as I know. This interface may support it: https://msdn.microsoft.com/en-us/library/windows/desktop/dd694868(v=vs.85).aspx . However, note the comment about only supporting DVB-T... and I'm pretty sure the driver implementations either don't support that interface or don't actually use blind scan.
Yes, some - maybe DVBSky only, if I recall correctly - tuner vendor SDKs include information about blind scan support. Other vendors such as TBS keep that information private or restricted, because it involves very low level access to the hardware/driver. The interface can change with different hardware and/or driver and/or firmware versions, and using the interface may possibly put the tuner into an unusable state.
No, TV Server (MediaPortal) currently does not support blind scanning.
No, I don't intend to add native support for blind scanning. It may be possible to add support through StreamReaderEx BDA or CrazyScan third party interface, I don't know. Even it is possible, it currently isn't on my TODO list.

Both

Only the 3 frequencies from posting #1. Communication with UM is very hard.

What XML file have you selected for scan?

Editing Germany.Unitymedia NRW.xml solves the issue (Thanks for the hint ), but i think tuning files should be updated. @mm1352000 : Do you still need log files?

No. If it is just a tuning detail update, please post the update here:

...or we could move this thread there.
